  • 7d308590a   [GFS2] Export lm_interface to kernel headers ... Browse Code »

    lm_interface.h has a few out of the tree clients such as GFS1
    and userland tools.

    Right now, these clients keeps a copy of the file in their build tree
    that can go out of sync.

    Move lm_interface.h to include/linux, export it to userland and
    clean up fs/gfs2 to use the new location.

  • e9fc2aa09   [GFS2] Update copyright, tidy up incore.h ... Browse Code »

    As per comments from Jan Engelhardt this
    updates the copyright message to say "version" in full rather than
    "v.2". Also incore.h has been updated to remove forward structure
    declarations which are not required.

    The gfs2_quota_lvb structure has now had endianess annotations added
    to it. Also quota.c has been updated so that we now store the
    lvb data locally in endian independant format to avoid needing
    a structure in host endianess too. As a result the endianess
    conversions are done as required at various points and thus the
    conversion routines in lvb.[ch] are no longer required. I've
    moved the one remaining constant in lvb.h thats used into lm.h
    and removed the unused lvb.[ch].

    I have not changed the HIF_ constants. That is left to a later patch
    which I hope will unify the gh_flags and gh_iflags fields of the
    struct gfs2_holder.

  • feaa7bba0   [GFS2] Fix unlinked file handling ... Browse Code »

    This patch fixes the way we have been dealing with unlinked,
    but still open files. It removes all limits (other than memory
    for inodes, as per every other filesystem) on numbers of these
    which we can support on GFS2. It also means that (like other
    fs) its the responsibility of the last process to close the file
    to deallocate the storage, rather than the person who did the
    unlinking. Note that with GFS2, those two events might take place
    on different nodes.

    Also there are a number of other changes:

    o We use the Linux inode subsystem as it was intended to be
    used, wrt allocating GFS2 inodes
    o The Linux inode cache is now the point which we use for
    local enforcement of only holding one copy of the inode in
    core at once (previous to this we used the glock layer).
    o We no longer use the unlinked "special" file. We just ignore it
    completely. This makes unlinking more efficient.
    o We now use the 4th block allocation state. The previously unused
    state is used to track unlinked but still open inodes.
    o gfs2_inoded is no longer needed
    o Several fields are now no longer needed (and removed) from the in
    core struct gfs2_inode
    o Several fields are no longer needed (and removed) from the in core
    superblock

    There are a number of future possible optimisations and clean ups
    which have been made possible by this patch.

  • 71b86f562   [GFS2] Further updates to dir and logging code ... Browse Code »

    This reduces the size of the directory code by about 3k and gets
    readdir() to use the functions which were introduced in the previous
    directory code update.

    Two memory allocations are merged into one. Eliminates zeroing of some
    buffers which were never used before they were initialised by
    other data.

    There is still scope for further improvement in the directory code.

    On the logging side, a hand created mutex has been replaced by a
    standard Linux mutex in the log allocation code.

  • c752666c1   [GFS2] Fix bug in directory code and tidy up ... Browse Code »

    Due to a typo, the dir leaf split operation was (for the first
    split in a directory) writing the new hash vaules at the
    wrong offset. This is now fixed.

    Also some other tidy ups are included:

    - We use GFS2's hash function for dentries (see ops_dentry.c) so that
    we don't have to keep recalculating the hash values.
    - A lot of common code is eliminated between the various directory
    lookup routines.
    - Better error checking on directory lookup (previously different
    routines checked for different errors)
    - The leaf split operation has a couple of redundant operations
    removed from it, so it should be faster.

    There is still further scope for further clean ups in the directory
    code, and readdir in particular could do with slimming down a bit.

  • c9fd43078   [GFS2] Tidy up mount code. ... Browse Code »

    We no longer lookup ".gfs2_admin" in the root directory in order to
    find it, but instead use the inode number given in the superblock.
    Both the root directory and the admin directory are now looked up using
    the same routine, so the redundant code is removed.

    Also, there is no longer a reference to the root inode in the
    GFS2 super block. When required this can be retreived via
    sb->s_root->d_inode instead.

    Assuming that we introduce a metadata filesystem type for GFS, then
    this is a first step towards that goal.

  • 5c676f6d3   [GFS2] Macros removal in gfs2.h ... Browse Code »

    As suggested by Pekka Enberg .

    The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h
    The other macros are gone from gfs2.h as (although not requested
    by Pekka Enberg) are a number of included header file which are now
    included individually. The inode number comparison function is
    now an inline function.

    The DT2IF and IF2DT may be addressed in a future patch.

  • 7359a19cc   [GFS2] Fix for root inode ref count bug ... Browse Code »

    Umount is now working correctly again. The bug was due to
    not getting an extra ref count when mounting the fs. We
    should have bumped it by two (once for the internal pointer
    to the root inode from the super block and once for the
    inode hanging off the dcache entry for root).

    Also this patch tidys up the code dealing with looking up
    and creating inodes. We now pass Linux inodes (with gfs2_inodes
    attached) rather than the other way around and this reduces code
    duplication in various places.

  • f42faf4fa   [GFS2] Add gfs2_internal_read() ... Browse Code »

    Add the new external read function. Its temporarily in jdata.c
    even though the protoype is in ops_file.h - this will change
    shortly. The current implementation will change to a page cache
    one when that happens.

    In order to effect the above changes, the various internal inodes
    now have Linux inodes attached to them. We keep the references to
    the Linux inodes, rather than the gfs2_inodes in the super block.

    In order to get everything to work correctly I've had to reorder
    the init sequence on mount (which I should probably have done
    earlier when .gfs2_admin was made visible).
