  • b9251b823   [PATCH] Fix reiserfs deadlock ... Browse Code »

    reiserfs_cache_default_acl() should return whether we successfully found
    the acl or not. We have to return correct value even if reiserfs_get_acl()
    returns error code and not just 0. Otherwise callers such as
    reiserfs_mkdir() can unnecessarily lock the xattrs and later functions such
    as reiserfs_new_inode() fail to notice that we have already taken the lock
    and try to take it again with obvious consequences.

  • 5274f052e   [PATCH] Introduce sys_splice() system call ... Browse Code »

    This adds support for the sys_splice system call. Using a pipe as a
    transport, it can connect to files or sockets (latter as output only).

    From the splice.c comments:

    "splice": joining two ropes together by interweaving their strands.

    This is the "extended pipe" functionality, where a pipe is used as
    an arbitrary in-memory buffer. Think of a pipe as a small kernel
    buffer that you can use to transfer data from one end to the other.

    The traditional unix read/write is extended with a "splice()" operation
    that transfers data buffers to or from a pipe buffer.

    Named by Larry McVoy, original implementation from Linus, extended by
    Jens to support splicing to files and fixing the initial implementation
    bugs.

  • 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)

    Increase the size of the buffer_head b_size field (only) for 64 bit platforms.
    Update some old and moldy comments in and around the structure as well.

    The b_size increase allows us to perform larger mappings and allocations for
    large I/O requests from userspace, which tie in with other changes allowing
    the get_block_t() interface to map multiple blocks at once.

  • 4b6a9316f   [PATCH] cpuset memory spread: slab cache filesystems ... Browse Code »

    Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD
    memory spreading.

    If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's
    in a cpuset with the 'memory_spread_slab' option enabled goes to allocate
    from such a slab cache, the allocations are spread evenly over all the
    memory nodes (task->mems_allowed) allowed to that task, instead of favoring
    allocation on the node local to the current cpu.

    The following inode and similar caches are marked SLAB_MEM_SPREAD:

    file cache

    fs/ufs/super.c ufs_inode_cache
    net/socket.c sock_inode_cache
    net/sunrpc/rpc_pipe.c rpc_inode_cache

    The choice of which slab caches to so mark was quite simple. I marked
    those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache,
    inode_cache, and buffer_head, which were marked in a previous patch. Even
    though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same
    potentially large file system i/o related slab caches as we need for memory
    spreading.

    Given that the rule now becomes "wherever you would have used a
    SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use
    the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain.
    Future file system writers will just copy one of the existing file system
    slab cache setups and tend to get it right without thinking.

    The bitmaps associated with generation numbers for directory entries
    are declared as an array of ints. On some platforms, this causes alignment

    The following patch uses the standard bitmap declaration macros to

    Unfortunately, the reiserfs_attrs_cleared bit in the superblock flag can
    lie. File systems have been observed with the bit set, yet still contain
    garbage in the stat data field, causing unpredictable results.

    This patch backs out the enable-by-default behavior.

    It eliminates the changes from: d50a5cd860ce721dbeac6a4f3c6e42abcde68cd8,

    Sometimes we call do_journal_end() with t_refcount == 0. If quota is
    turned on and we happen to have some inode with preallocation bad things
    happen as we try to use the current handle for quota operations. Checks
    for t_refcount in journal_begin() fail and we Oops. We raise t_refcount to
    make those checks happy. We should not cause any bad as all the needed
    quota blocks should be already attached to the transaction (they were
    attached to the transaction when we allocated those preallocation blocks).

    To allow various options to work per-mount instead of per-sb we need a
    struct vfsmount when updating ctime and mtime. This preparation patch
    replaces the inode_update_time routine with a file_update_atime routine so
    we can easily get at the vfsmount. (and the file makes more sense in this
    context anyway). Also get rid of the unused second argument - we always
    want to update the ctime when calling this routine.
