* ocfs: simplify symlink handlingAl Viro2012-05-294-104/+31

| * | ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita2011-12-012-5/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

The credit calculation in ocfs2_link_credits() did not correctly account for adding an entry that exactly fills a dirblock that triggers removing that dirblock by changing the pointer in the previous block in the list. The credit calculation did not account for that previous block. To expose, do: mkfs.ocfs2 -b 512 -M local /dev/sdX mount /dev/sdX /ocfs2 mkdir /ocfs2/linkdir touch /ocfs2/linkdir/file1 for i in `seq 1 29` ; do link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklink$i; done rm -f /ocfs2/linkdir/linklinklinklinklinklink10 sleep 8 link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Note: The link names have been crafted for a 512 byte blocksize. Reproducing with a larger blocksize will require longer (or more) links. The sleep is important. We want jbd2 to commit the transaction so that the missing block does not piggy back on account of the previous transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we deleting a direntry from a directory, if it's the first in a block we invalid it by setting inode to 0; otherwise, we merge the deleted one to the prior and contiguous direntry. And we don't truncate directories. There is a problem for the later case since inode is not set to 0. This problem happens when the caller passes a file position as parameter to ocfs2_dir_foreach_blk(). If the position happens to point to a stale(not the first, deleted in betweens of ocfs2_dir_foreach_blk()s) direntry, we are not able to recognize its staleness. So that we treat it as a live one wrongly. The fix is to set inode to 0 in both cases indicating the direntry is stale. This won't introduce additional IOs.

SEEK_HOLE sets the file pointer to the start of either a hole or an unwritten (preallocated) extent, that is greater than or equal to the supplied offset. SEEK_DATA sets the file pointer to the start of an allocated extent (not unwritten) that is greater than or equal to the supplied offset. If the supplied offset is on a desired region, then the file pointer is set to it. Offsets greater than or equal to the file size return -ENXIO. Unwritten (preallocated) extents are considered holes because the file system treats reads to such regions in the same way as it does to holes. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
