  • cd81a4bac   [GFS2] Addendum patch 2 for gfs2_grow ... Browse Code »

    This addendum patch 2 corrects three things:

    1. It fixes a stupid mistake in the previous addendum that broke gfs2.
    Ref: https://www.redhat.com/archives/cluster-devel/2007-May/msg00162.html
    2. It fixes a problem that Dave Teigland pointed out regarding the
    external declarations in ops_address.h being in the wrong place.
    3. It recasts a couple more %llu printks to (unsigned long long)
    as requested by Steve Whitehouse.

    I would have loved to put this all in one revised patch, but there was
    a rush to get some patches for RHEL5. Therefore, the previous patches
    were applied to the git tree "as is" and therefore, I'm posting another
    addendum. Sorry.

  • 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.

  • 4340fe625   [GFS2] Add generation number ... Browse Code »

    This adds a generation number for the eventual use of NFS to the
    ondisk inode. Its backward compatible with the current code since
    it doesn't really matter what the generation number is to start with,
    and indeed since its set to zero, due to it being taken from padding
    in both the inode and rgrp header, it should be fine.

    The eventual plan is to use this rather than no_formal_ino in the
    NFS filehandles. At that point no_formal_ino will be unused.

    At the same time we also add a releasepages call back to the
    "normal" address space for gfs2 inodes. Also I've removed a
    one-linrer function thats not required any more.

  • 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.
