  • 02c24a821   fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers ... Browse Code »

    Btrfs needs to be able to control how filemap_write_and_wait_range() is called
    in fsync to make it less of a painful operation, so push down taking i_mutex and
    the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
    file systems can drop taking the i_mutex altogether it seems, like ext3 and
    ocfs2. For correctness sake I just pushed everything down in all cases to make
    sure that we keep the current behavior the same for everybody, and then each
    individual fs maintainer can make up their mind about what to do from there.
    Thanks,

  • a9185b41a   pass writeback_control to ->write_inode ... Browse Code »

    This gives the filesystem more information about the writeback that
    is happening. Trond requested this for the NFS unstable write handling,
    and other filesystems might benefit from this too by beeing able to
    distinguish between the different callers in more detail.

  • c47587955   sanitize ->fsync() for affs ... Browse Code »

    unfortunately, for affs (especially for affs directories) we have
    no real way to keep track of metadata ownership. So we have to
    do more or less what file_fsync() does, but we do *not* need to
    call write_super() there.

  • dca3c3365   [PATCH] fix reservation discarding in affs ... Browse Code »

    - remove affs_put_inode, so preallocations aren't discared unnecessarily
    often.
    - remove affs_drop_inode, it's called with a spinlock held, so it can't
    use a mutex.
    - make i_opencnt atomic
    - avoid direct b_count manipulations
    - a few allocation failure fixes, so that these are more gracefully
    handled now.

  • 210f85596   iget: stop AFFS from using iget() and read_inode() ... Browse Code »

    Stop the AFFS filesystem from using iget() and read_inode(). Replace
    affs_read_inode() with affs_iget(), and call that instead of iget().
    affs_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

    affs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

  • 2be3c7904   [PATCH] affs: implement ->drop_inode ... Browse Code »

    affs wants to truncate the inode when the last user goes away, currently it
    does that through a potentially racy i_count check in ->put_inode. But we
    already have a method that's called just after the we dropped the last
    reference, ->drop_inode. This patch implements affs_drop_inode to take
    advantage of this.

  • 754661f14   [PATCH] mark struct inode_operations const 1 ... Browse Code »

    Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
