  • 70246286e   block: get rid of bio_rw and READA ... Browse Code »

    These two are confusing leftover of the old world order, combining
    values of the REQ_OP_ and REQ_ namespaces. For callers that don't
    special case we mostly just replace bi_rw with bio_data_dir or
    op_is_write, except for the few cases where a switch over the REQ_OP_
    values makes more sense. Any check for READA is replaced with an
    explicit check for REQ_RAHEAD. Also remove the READA alias for
    REQ_RAHEAD.

  • 066b9cded   udf: Use separate buffer for copying split names ... Browse Code »

    Code in udf_find_entry() and udf_readdir() used the same buffer for
    storing filename that was split among blocks and for the resulting
    filename in utf8. This worked because udf_get_filename() first
    internally copied the name into a different buffer and only then
    performed a conversion into the destination buffer. However we want to
    get rid of intermediate buffers so use separate buffer for converted
    name and name split between blocks so that we don't have the same source
    and destination buffer when converting split names.

  • 0e5cc9a40   udf: Check path length when reading symlink ... Browse Code »

    Symlink reading code does not check whether the resulting path fits into
    the page provided by the generic code. This isn't as easy as just
    checking the symlink size because of various encoding conversions we
    perform on path. So we have to check whether there is still enough space
    in the buffer on the fly.

  • 9db9f9e31   udf: Remove unnecessary bkl usages ... Browse Code »

    The udf_readdir(), udf_lookup(), udf_create(), udf_mknod(), udf_mkdir(),
    udf_rmdir(), udf_link(), udf_get_parent() and udf_unlink() seems already
    adequately protected by i_mutex held by VFS invoking calls. The udf_rename()
    instead should be already protected by lock_rename again by VFS. The
    udf_ioctl(), udf_fill_super() and udf_evict_inode() don't requires any further
    protection.

    This work was supported by a hardware donation from the CE Linux Forum.

  • 1b061d924   rename the generic fsync implementations ... Browse Code »

    We don't name our generic fsync implementations very well currently.
    The no-op implementation for in-memory filesystems currently is called
    simple_sync_file which doesn't make too much sense to start with,
    the the generic one for simple filesystems is called simple_fsync
    which can lead to some confusion.

    This patch renames the generic file fsync method to generic_file_fsync
    to match the other generic_file_* routines it is supposed to be used
    with, and the no-op implementation to noop_fsync to make it obvious
    what to expect. In addition add some documentation for both methods.

  • ca572727d   fs/: do not fallback to default_llseek() when readdir() uses BKL ... Browse Code »

    Do not use the fallback default_llseek() if the readdir operation of the
    filesystem still uses the big kernel lock.

    Since llseek() modifies
    file->f_pos of the directory directly it may need locking to not confuse
    readdir which usually uses file->f_pos directly as well

    Since the special characteristics of the BKL (unlocked on schedule) are
    not necessary in this case, the inode mutex can be used for locking as
    provided by generic_file_llseek(). This is only possible since all
    filesystems, except reiserfs, either use a directory as a flat file or
    with disk address offsets. Reiserfs on the other hand uses a 32bit hash
    off the filename as the offset so generic_file_llseek() can get used as
    well since the hash is always smaller than sb->s_maxbytes (= (512 << 32) -
    blocksize).

    Use sector_t and loff_t for file offsets in UDF filesystem. Otherwise an
    overflow may occur for long files. Also make inode_bmap() return offset in
    the extent in number of blocks instead of number of bytes - for most
    callers this is more convenient.

  • 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)

    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!
