  • ebfc3b49a   don't pass nameidata to ->create() ... Browse Code »

    boolean "does it have to be exclusive?" flag is passed instead;
    Local filesystem should just ignore it - the object is guaranteed
    not to be there yet.

  • 00cd8dd3b   stop passing nameidata to ->lookup() ... Browse Code »

    Just the flags; only NFS cares even about that, but there are
    legitimate uses for such argument. And getting rid of that
    completely would require splitting ->lookup() into a couple
    of methods (at least), so let's leave that alone for now...

    Pull vfs changes from Al Viro.
    "A lot of misc stuff. The obvious groups:
    * Miklos' atomic_open series; kills the damn abuse of
    ->d_revalidate() by NFS, which was the major stumbling block for
    all work in that area.
    * ripping security_file_mmap() and dealing with deadlocks in the
    area; sanitizing the neighborhood of vm_mmap()/vm_munmap() in
    general.
    * ->encode_fh() switched to saner API; insane fake dentry in
    mm/cleancache.c gone.
    * assorted annotations in fs (endianness, __user)
    * parts of Artem's ->s_dirty work (jff2 and reiserfs parts)
    * ->update_time() work from Josef.
    * other bits and pieces all over the place.

    Normally it would've been in two or three pull requests, but
    signal.git stuff had eaten a lot of time during this cycle ;-/"

    Fix up trivial conflicts in Documentation/filesystems/vfs.txt (the
    'truncate_range' inode method was removed by the VM changes, the VFS
    update adds an 'update_time()' method), and in fs/btrfs/ulist.[ch] (due
    to sparse fix added twice, with other changes nearby).

    The PRINTK() macro isn't really used. Let's just remove it because it
    is ugly and out of date.

  • dbd5768f8   vfs: Rename end_writeback() to clear_inode() ... Browse Code »

    After we moved inode_sync_wait() from end_writeback() it doesn't make sense
    to call the function end_writeback() anymore. Rename it to clear_inode()
    which well says what the function really does - set I_CLEAR flag.

    Standardize the style for compiler based printf format verification.
    Standardized the location of __printf too.

    Done via script and a little typing.

    grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \

  • 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,

  • 06222e491   fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek ... Browse Code »

    This converts everybody to handle SEEK_HOLE/SEEK_DATA properly. In some cases
    we just return -EINVAL, in others we do the normal generic thing, and in others
    we're simply making sure that the properly due-dilligence is done. For example
    in NFS/CIFS we need to make sure the file size is update properly for the
    SEEK_HOLE and SEEK_DATA case, but since it calls the generic llseek stuff itself
    that is all we have to do. Thanks,

    Only a few file systems need this. Start by pushing it down into each
    rename method (except gfs2 and xfs) so that it can be dealt with on a
    per-fs basis.

    This serves no useful purpose that I can discern. All callers (rename,
    rmdir) hold their own reference to the dentry.

    A quick audit of all file systems showed no relevant checks on the value
    of d_count in vfs_rmdir/vfs_rename_dir paths.
