* [PATCH] x86: do not recompile boot for each buildSam Ravnborg2007-07-181-1/+1

* [x86 setup] Save/restore DS around invocations of INT 10hH. Peter Anvin2007-07-182-2/+9
| | | | | | | | | | | | | There exists at least one card, Trident TVGA8900CL (BIOS dated 1992/9/8) which clobbers DS when "scrolling in an SVGA text mode of more than 800x600 pixels." Although we are extremely unlikely to run into that situation, it is cheap insurance to save and restore DS, and it only adds a grand total of 50 bytes to the total output.

* [x86 setup] VGA: Clear the Protect bit before setting the vertical heightH. Peter Anvin2007-07-181-1/+6
| | | | | | | | | | | | | | | If the user has asked for the vertical height registers to be recomputed by setting bit 15 in the video mode number, we do so without clearing the Protect bit in the Vertical Retrace Register before setting the Overflow register. As a result, if the VGA BIOS had set the Protect bit, the write to the Overflow register will be dropped, and bits [9:8] of the vertical height will be left unchanged. This is a bug imported from the assembly version of this code. It was pointed out by Etienne Lorrain. Cc: Etienne Lorrain <etienne_lorrain@yahoo.fr> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* [x86 setup] Fix assembly constraintsH. Peter Anvin2007-07-186-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | Fix incorrect assembly constraints. In particular, fix memory constraints used inside push..pop, which can cause invalid operation since gcc may generate %esp-relative references. Additionally: outl() should have "dN" not "dn". query_mca() shouldn't listen 16/32-bit registers in an 8-bit only context. has_eflag(): the "mask" is only used well after both the stack pointer and the output registers have been touched; this requires the output registers to be earlyclobbers (=&) and the input to exclude memory (so "ri", not "g").

| * ext4: extent macros cleanupDmitry Monakhov2007-07-181-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the EXT_LAST_INDEX macro; that's what it's there for. Clean up ext4_ext_ext_grow_indepth() so the correct EXT_FIRST_INDEX or EXT_FIRST_MACRO is used as necessary. The two macros are equivalent, so the C will collapse the if statement out, but it makes the code much more readable.

| * ext4: Remove 65000 subdirectory limitAndreas Dilger2007-07-182-15/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to ext4 for allowing more than 65000 subdirectories. Currently the maximum number of subdirectories is capped at 32000. If we exceed 65000 subdirectories in an htree directory it sets the inode link count to 1 and no longer counts subdirectories. The directory link count is not actually used when determining if a directory is empty, as that only counts subdirectories and not regular files that might be in there. A EXT4_FEATURE_RO_COMPAT_DIR_NLINK flag has been added and it is set if the subdir count for any directory crosses 65000. A later fsck will clear EXT4_FEATURE_RO_COMPAT_DIR_NLINK if there are no longer any directory with >65000 subdirs.

| * ext4: Expand extra_inodes space per the s_{want,min}_extra_isize fields Kalpak Shah2007-07-184-8/+347
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make sure that existing ext3 filesystems can also avail the new fields that have been added to the ext4 inode. We use s_want_extra_isize and s_min_extra_isize to decide by how much we should expand the inode. If EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature is set then we expand the inode by max(s_want_extra_isize, s_min_extra_isize , sizeof(ext4_inode) - EXT4_GOOD_OLD_INODE_SIZE) bytes. Actually it is still an open question about whether users should be able to set s_*_extra_isize smaller than the known fields or not. This patch also adds the functionality to expand inodes to include the newly added fields. We start by trying to expand by s_want_extra_isize bytes and if its fails we try to expand by s_min_extra_isize bytes. This is done by changing the i_extra_isize if enough space is available in the inode and no EAs are present. If EAs are present and there is enough space in the inode then the EAs in the inode are shifted to make space. If enough space is not available in the inode due to the EAs then 1 or more EAs are shifted to the external EA block. In the worst case when even the external EA block does not have enough space we inform the user that some EA would need to be deleted or s_min_extra_isize would have to be reduced.

| * ext4: Add nanosecond timestampsKalpak Shah2007-07-189-25/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds nanosecond timestamps for ext4. This involves adding *time_extra fields to the ext4_inode to extend the timestamps to 64-bits. Creation time is also added by this patch. These extended fields will fit into an inode if the filesystem was formatted with large inodes (-I 256 or larger) and there are currently no EAs consuming all of the available space. For new inodes we always reserve enough space for the kernel's known extended fields, but for inodes created with an old kernel this might not have been the case. So this patch also adds the EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature flag(ro-compat so that older kernels can't create inodes with a smaller extra_isize). which indicates if the fields fitting inside s_min_extra_isize are available or not. If the expansion of inodes if unsuccessful then this feature will be disabled. This feature is only enabled if requested by the sysadmin. None of the extended inode fields is critical for correct filesystem operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | The jbd2-debug file used to be located in /proc/sys/fs/jbd2-debug, but it incorrectly used create_proc_entry() instead of the sysctl routines, and no proc entry was ever created. Instead of fixing this we might as well move the jbd2-debug file to debugfs which would be the preferred location for this kind of tunable. The new location is now /sys/kernel/debug/jbd2/jbd2-debug.

| * Change on-disk format to support 2^15 uninitialized extentsAmit Arora2007-07-182-7/+52
| | | | | | | | | | | | | | | | | | | | | | | | This change was suggested by Andreas Dilger. This patch changes the EXT_MAX_LEN value and extent code which marks/checks uninitialized extents. With this change it will be possible to have initialized extents with 2^15 blocks (earlier the max blocks we could have was 2^15 - 1). This way we can have better extent-to-block alignment. Now, maximum number of blocks we can have in an initialized extent is 2^15 and in an uninitialized extent is 2^15 - 1. Signed-off-by: Amit Arora <aarora@in.ibm.com>

| | | | | | | | | | | | | | | | | | This patch adds write support to the uninitialized extents that get created when a preallocation is done using fallocate().

| * fallocate support in ext4Amit Arora2007-07-174-41/+232
| | | | | | | | | | | | | | | | | | | | | | | | This patch implements ->fallocate() inode operation in ext4. With this patch users of ext4 file systems will be able to use fallocate() system call for persistent preallocation. Current implementation only supports preallocation for regular files (directories not supported as of date) with extent maps. This patch does not support block-mapped files currently. Only FALLOC_ALLOCATE and FALLOC_RESV_SPACE modes are being supported as of now. Signed-off-by: Amit Arora <aarora@in.ibm.com>
| * sys_fallocate() implementation on i386, x86_64 and powerpcAmit Arora2007-07-1712-2/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fallocate() is a new system call being proposed here which will allow applications to preallocate space to any file(s) in a file system. Each file system implementation that wants to use this feature will need to support an inode operation called ->fallocate(). Applications can use this feature to avoid fragmentation to certain level and thus get faster access speed. With preallocation, applications also get a guarantee of space for particular file(s) - even if later the the system becomes full. Currently, glibc provides an interface called posix_fallocate() which can be used for similar cause. Though this has the advantage of working on all file systems, but it is quite slow (since it writes zeroes to each block that has to be preallocated). Without a doubt, file systems can do this more efficiently within the kernel, by implementing the proposed fallocate() system call. It is expected that posix_fallocate() will be modified to call this new system call first and incase the kernel/filesystem does not implement it, it should fall back to the current implementation of writing zeroes to the new blocks. ToDos: 1. Implementation on other architectures (other than i386, x86_64, and ppc). Patches for s390(x) and ia64 are already available from previous posts, but it was decided that they should be added later once fallocate is in the mainline. Hence not including those patches in this take. 2. Changes to glibc, a) to support fallocate() system call b) to make posix_fallocate() and posix_fallocate64() call fallocate() Signed-off-by: Amit Arora <aarora@in.ibm.com>

| * | UBI: minor comma fixArtem Bityutskiy2007-07-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use coma at the the last elements of structure initializer. Daniel Stone's explanation: Because it turns: - .attr = foo + .attr = foo, + .bar = baz into: + .bar = baz, i.e., far less likely to screw up a merge.
