    When I enable EXT2_XATTR_DEBUG in fs/ext2/xattr.c I get a build error stating
    the following:

    CC fs/ext2/xattr.o
    fs/ext2/xattr.c: In function 'ext2_xattr_cache_insert':
    fs/ext2/xattr.c:841: error: dereferencing pointer to incomplete type
    fs/ext2/xattr.c:846: error: dereferencing pointer to incomplete type
    make[2]: *** [fs/ext2/xattr.o] Error 1
    make[1]: *** [fs/ext2] Error 2
    make: *** [fs] Error 2

    These lines reference ext2_xattr_cache->c_entry_count which is defined
    in struct mb_cache. struct mb_cache is currently only defined in fs/mbcache.c.
    Moving struct mb_cache definition to include/linux/mbcache.h to resolve the
    issue.

  • 2aec7c523   mbcache: Remove unused features ... Browse Code »

    The mbcache code was written to support a variable number of indexes,
    but all the existing users use exactly one index. Simplify to code to
    support only that case.

    There are also no users of the cache entry free operation, and none of
    the users keep extra data in cache entries. Remove those features as
    well.

  • 335e92e8a   vfs: fix possible deadlock in ext2, ext3, ext4 when using xattrs ... Browse Code »

    mb_cache_entry_alloc() was allocating cache entries with GFP_KERNEL. But
    filesystems are calling this function while holding xattr_sem so possible
    recursion into the fs violates locking ordering of xattr_sem and transaction
    start / i_mutex for ext2-4. Change mb_cache_entry_alloc() so that filesystems
    can specify desired gfp mask and use GFP_NOFS from all of them.

  • 27496a8c6   [PATCH] gfp_t: fs/* ... Browse Code »

    - ->releasepage() annotated (s/int/gfp_t), instances updated
    - missing gfp_t in fs/* added
    - fixed misannotation from the original sweep caught by bitwise checks:
    XFS used __nocast both for gfp_t and for flags used by XFS allocator.
    The latter left with unsigned int __nocast; we might want to add a
    different type for those but for now let's leave them alone. That,
    BTW, is a case when __nocast use had been actively confusing - it had
    been used in the same code for two different and similar types, with
    no way to catch misuses. Switch of gfp_t to bitwise had caught that
    immediately...

    One tricky bit is left alone to be dealt with later - mapping->flags is
    a mix of gfp_t and error indications. Left alone for now.

    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!
