  • c37650161   fs: add sync_inode_metadata ... Browse Code »

    Add a new helper to write out the inode using the writeback code,
    that is including the correct dirty bit and list manipulation. A few
    of filesystems already opencode this, and a lot of others should be
    using it instead of using write_inode_now which also writes out the
    data.

  • c15271f4e   ext2: Add ext2_sb_info s_lock spinlock ... Browse Code »

    Add a spinlock that protects against concurrent modifications of
    s_mount_state, s_blocks_last, s_overhead_last and the content of the
    superblock's buffer pointed to by sbi->s_es. The spinlock is now used in
    ext2_xattr_update_super_block() which was setting the
    EXT2_FEATURE_COMPAT_EXT_ATTR flag on the superblock without protection
    before. Likewise the spinlock is used in ext2_show_options() to have a
    consistent view of the mount options.

    This is a preparation patch for removing the BKL from ext2 in the next
    patch.

  • 5dd4056db   dquot: cleanup space allocation / freeing routines ... Browse Code »

    Get rid of the alloc_space, free_space, reserve_space, claim_space and
    release_rsv dquot operations - they are always called from the filesystem
    and if a filesystem really needs their own (which none currently does)
    it can just call into it's own routine directly.

    Move shared logic into the common __dquot_alloc_space,
    dquot_claim_space_nodirty and __dquot_free_space low-level methods,
    and rationalize the wrappers around it to move as much as possible
    code into the common block for CONFIG_QUOTA vs not. Also rename
    all these helpers to be named dquot_* instead of vfs_dq_*.

  • 431547b3c   sanitize xattr handler prototypes ... Browse Code »

    Add a flags argument to struct xattr_handler and pass it to all xattr
    handler methods. This allows using the same methods for multiple
    handlers, e.g. for the ACL methods which perform exactly the same action
    for the access and default ACLs, just using a different underlying
    attribute. With a little more groundwork it'll also allow sharing the
    methods for the regular user/trusted/secure handlers in extN, ocfs2 and
    jffs2 like it's already done for xfs in this patch.

    Also change the inode argument to the handlers to a dentry to allow
    using the handlers mechnism for filesystems that require it later,
    e.g. cifs.

  • 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.

  • b2f49033d   [PATCH] fix deadlock in ext2 ... Browse Code »

    Fix a deadlock possible in the ext2 file system implementation. This
    deadlock occurs when a file is removed from an ext2 file system which was
    mounted with the "sync" mount option.

    The problem is that ext2_xattr_delete_inode() was invoking the routine,
    sync_dirty_buffer(), using a buffer head which was previously locked via
    lock_buffer(). The first thing that sync_dirty_buffer() does is to lock
    the buffer head that it was passed. It does this via lock_buffer(). Oops.

    The solution is to unlock the buffer head in ext2_xattr_delete_inode()
    before invoking sync_dirty_buffer(). This makes the code in
    ext2_xattr_delete_inode() obey the same locking rules as all other callers
    of sync_dirty_buffer() in the ext2 file system implementation.

    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!
