      Revert "ext2/ext3/ext4: add block bitmap validation" · 0b832a4b
      Linus Torvalds 提交于
      This reverts commit 7c9e69fa, fixing up
      conflicts in fs/ext4/balloc.c manually.
      
      The cost of doing the bitmap validation on each lookup - even when the
      bitmap is cached - is absolutely prohibitive.  We could, and probably
      should, do it only when adding the bitmap to the buffer cache.  However,
      right now we are better off just reverting it.
      
      Peter Zijlstra measured the cost of this extra validation as a 85%
      decrease in cached iozone, and while I had a patch that took it down to
      just 17% by not being _quite_ so stupid in the validation, it was still
      a big slowdown that could have been avoided by just doing it right.

      fix inode_table test in ext234_check_descriptors · 780dcdb2
      Eric Sandeen 提交于
      ext[234]_check_descriptors sanity checks block group descriptor geometry at
      mount time, testing whether the block bitmap, inode bitmap, and inode table
      reside wholly within the blockgroup.  However, the inode table test is off
      by one so that if the last block in the inode table resides on the last
      block of the block group, the test incorrectly fails.  This is because it
      tests the last block as (start + length) rather than (start + length - 1).
      
      This can be seen by trying to mount a filesystem made such as:
      
       mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024
      
      which yields:
      
       EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)!
       EXT2-fs: group descriptors corrupted!
      
      There is a similar bug in e2fsprogs, patch already sent for that.
      
      (I wonder if inside(), outside(), and/or in_range() should someday be
      used in this and other tests throughout the ext filesystems...)

      xip sendfile removal · d054fe3d
      Carsten Otte 提交于
      This patch removes xip_file_sendfile, the sendfile implementation for
      xip without replacement. Those customers that use xip on s390 are not
      using sendfile() as far as we know, and so far s390 is the only platform
      this could potentially be used on so far.
      Having sendfile is not a popular feature for execute in place file
      systems, however we have a working implementation of splice_read() based
      on fs/splice.c if anyone asks for it.
      At this point in time, it does not seem preferable to merge
      splice_read() for xip because it causes extra maintenence effort due to
      code duplication and it requires struct page behind the xip memory
      segment. We'd like to get rid of that in favor of supporting flash based
      embedded platforms (Monta Vista work) soon.

      sendfile: remove .sendfile from filesystems that use generic_file_sendfile() · 5ffc4ef4
      Jens Axboe 提交于
      They can use generic_file_splice_read() instead. Since sys_sendfile() now
      prefers that, there should be no change in behaviour.
