* [PATCH] reiserfs: reiserfs: check for files > 2GB on 3.5.x disksJeff Mahoney2006-02-011-0/+17
| | | | | | | | | | When a filesystem has been converted from 3.5.x to 3.6.x, we need an extra check during file write to make sure we are not trying to make a 3.5.x file > 2GB.

* [PATCH] reiserfs: reiserfs hang and performance fix for data=journal modeChris Mason2006-02-012-5/+21
| | | | | | | | | | | | | | In data=journal mode, reiserfs writepage needs to make sure not to trigger transactions while being run under PF_MEMALLOC. This patch makes sure to redirty the page instead of forcing a transaction start in this case. Also, calling filemap_fdata* in order to trigger io on the block device can cause lock inversions on the page lock. Instead, do simple batching from flush_commit_list.

* [PATCH] resierfs: fix reiserfs_invalidatepage race against data=orderedChris Mason2006-02-012-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | After a transaction has closed but before it has finished commit, there is a window where data=ordered mode requires invalidatepage to pin pages instead of freeing them. This patch fixes a race between the invalidatepage checks and data=ordered writeback, and it also adds a check to the reiserfs write_ordered_buffers routines to write any anonymous buffers that were dirtied after its first writeback loop. That bug works like this: proc1: transaction closes and a new one starts proc1: write_ordered_buffers starts processing data=ordered list proc1: buffer A is cleaned and written proc2: buffer A is dirtied by another process proc2: File is truncated to zero, page A goes through invalidatepage proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs journal head, pins it proc1: write_ordered_buffers frees the journal head on buffer A At this point, buffer A stays dirty forever Signed-off-by: Chris Mason <mason@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] s390: overflow in sched_clockJan Glauber2006-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | The least significant bit of the TOD clock value returned by get_clock is the 4096th part of a microsecond. To get to nanoseconds the value needs to be divided by 4096 and multiplied with 1000. The current method multiplies first and then shifts the value to make the result as precise as possible. The disadvantage is that the multiplication with 1000 will overflow shortly after 52 days. sched_clock is used by the scheduler for time stamp deltas, if an overflow occurs between two time stamps the scheduler will get confused. With the patch the problem occurs only after approx. one year, so the chance to run into this overflow is extremly low.

| | | | | | | | | | | | | | | | | Olaf Hering <olh@suse.de> Olaf reported UML doesn't build for him with a clear analisys of what happened - we're using NR_CPUS in files linked against glibc headers. Seems like it defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS undeclared. The fix is to move the declaration away from that header file and move it in asm-um headers, and to add that header where needed.

* [PATCH] VMSPLIT config optionsMark Lord2006-02-012-2/+39
| | | | | | | | | | | | | | | | | | | | | | | | Enable selection of different user/kernel VM splits for i386, including an optimized mode for 1GB physical RAM, which gives the kernel a direct (non HIGHMEM) mapping to the entire 1GB rather than just the first 896MB. There is a similarly a similarly optimized mode for machines with exactly 2GB of physical RAM. This can speed up the kernel by avoiding having to create/destroy temporary HIGHMEM mappings, and by not having to include HIGHMEM support at all on such machines. The flip side is that there's less virtual addressing left for userspace in these alternatives, and some binary-only kernel modules may misbehave unless rebuilt with the same VMSPLIT option as the main kernel image.
