  • 302bf2f32   ext2/3/4: delete unneeded includes of module.h ... Browse Code »

    Delete any instances of include module.h that were not strictly
    required. In the case of ext2, the declaration of MODULE_LICENSE
    etc. were in inode.c but the module_init/exit were in super.c, so
    relocate the MODULE_LICENCE/AUTHOR block to super.c which makes it
    consistent with ext3 and ext4 at the same time.

  • 189e868fa   ext4: fix fsx truncate failure ... Browse Code »
    44

    While running extended fsx tests to verify the first
    two patches, a similar bug was also found in the
    truncate operation.

    This bug happens because the truncate routine only zeros
    the unblock aligned portion of the last page. This means
    that the block aligned portions of the page appearing after
    i_size are left unzeroed, and the buffer heads still mapped.

    This bug is corrected by using ext4_discard_partial_page_buffers
    in the truncate routine to zero the partial page and unmap
    the buffer headers.

  • dccaf33fa   ext4: flush any pending end_io requests before DIO reads w/dioread_nolock ... Browse Code »
    1

    There is a race between ext4 buffer write and direct_IO read with
    dioread_nolock mount option enabled. The problem is that we clear
    PageWriteback flag during end_io time but will do
    uninitialized-to-initialized extent conversion later with dioread_nolock.
    If an O_direct read request comes in during this period, ext4 will return
    zero instead of the recently written data.

    This patch checks whether there are any pending uninitialized-to-initialized
    extent conversion requests before doing O_direct read to close the race.
    Note that this is just a bandaid fix. The fundamental issue is that we
    clear PageWriteback flag before we really complete an IO, which is
    problem-prone. To fix the fundamental issue, we may need to implement an
    extent tree cache that we can use to look up pending to-be-converted extents.

    * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (60 commits)
    ext4: prevent memory leaks from ext4_mb_init_backend() on error path
    ext4: use EXT4_BAD_INO for buddy cache to avoid colliding with valid inode #
    ext4: use ext4_msg() instead of printk in mballoc
    ext4: use ext4_kvzalloc()/ext4_kvmalloc() for s_group_desc and s_group_info
    ext4: introduce ext4_kvmalloc(), ext4_kzalloc(), and ext4_kvfree()
    ext4: use the correct error exit path in ext4_init_inode_table()
    ext4: add missing kfree() on error return path in add_new_gdb()
    ext4: change umode_t in tracepoint headers to be an explicit __u16
    ext4: fix races in ext4_sync_parent()
    ext4: Fix overflow caused by missing cast in ext4_fallocate()
    ext4: add action of moving index in ext4_ext_rm_idx for Punch Hole
    ext4: simplify parameters of reserve_backup_gdb()
    ext4: simplify parameters of add_new_gdb()
    ext4: remove lock_buffer in bclean() and setup_new_group_blocks()
    ext4: simplify journal handling in setup_new_group_blocks()
    ext4: let setup_new_group_blocks() set multiple bits at a time
    ext4: fix a typo in ext4_group_extend()
    ext4: let ext4_group_add_blocks() handle 0 blocks quickly
    ext4: let ext4_group_add_blocks() return an error code
    ext4: rename ext4_add_groupblocks() to ext4_group_add_blocks()
    ...

    Fix up conflict in fs/ext4/inode.c: commit aacfc19c626e ("fs: simplify
    the blockdev_direct_IO prototype") had changed the ext4_ind_direct_IO()
    function for the new simplified calling convention, while commit
    dae1e52cb126 ("ext4: move ext4_ind_* functions from inode.c to
    indirect.c") moved the function to another file.
