      "message": "GFS2: high time to take some time over atime\n\nUntil now, we\u0027ve used the same scheme as GFS1 for atime. This has failed\nsince atime is a per vfsmnt flag, not a per fs flag and as such the\n\"noatime\" flag was not getting passed down to the filesystems. This\npatch removes all the \"special casing\" around atime updates and we\nsimply use the VFS\u0027s atime code.\n\nThe net result is that GFS2 will now support all the same atime related\nmount options of any other filesystem on a per-vfsmnt basis. We do lose\nthe \"lazy atime\" updates, but we gain \"relatime\". We could add lazy\natime to the VFS at a later date, if there is a requirement for that\nvariant still - I suspect relatime will be enough.\n\nAlso we lose about 100 lines of code after this patch has been applied,\nand I have a suspicion that it will speed things up a bit, even when\natime is \"on\". So it seems like a nice clean up as well.\n\nFrom a user perspective, everything stays the same except the loss of\nthe per-fs atime quantum tweekable (ought to be per-vfsmnt at the very\nleast, and to be honest I don\u0027t think anybody ever used it) and that a\nnumber of options which were ignored before now work correctly.\n\nPlease let me know if you\u0027ve got any comments. I\u0027m pushing this out\nearly so that you can all see what my plans are.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

It uses a bunch of arbitrary constants which are unlikely to be\n    correct for any particular situation and for which the tuning seems\n    to be a black art.\n 5.

The\ncode was too complicated and also hurts performance badly in the\ncase that the getdents64/readdir call isn\u0027t being followed by\nstat() and it wasn\u0027t even getting it right all the time when it\nwas.\n\nAs a result, on my test box an \"ls\" of a directory containing 250000\nfiles fell from about 7mins (freshly mounted, so nothing cached) to\nbetween about 15 to 25 seconds. When the directory content was cached,\nthe time taken fell from about 3mins to about 4 or 5 seconds.\n\nInterestingly in the cached case, running \"ls -l\" once reduced the time\ntaken for subsequent runs of \"ls\" to about 6 secs even without this\npatch. Now it turns out that there was a special case of glocks being\nused for prefetching the metadata, but because of the timeouts for these\nlocks (set to 10 secs) the metadata was being timed out before it was\nbeing used and this the prefetch code was constantly trying to prefetch\nthe same data over and over.\n\nCalling \"ls -l\" meant that the inodes were brought into memory and once\nthe inodes are cached, the glocks are not disposed of until the inodes\nare pushed out of the cache, thus extending the lifetime of the glocks,\nand thus bringing down the time for subsequent runs of \"ls\"\nconsiderably.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

      "message": "[GFS2] Update copyright, tidy up incore.h\n\nAs per comments from Jan Engelhardt \u003cjengelh@linux01.gwdg.de\u003e this\nupdates the copyright message to say \"version\" in full rather than\n\"v.2\". Also incore.h has been updated to remove forward structure\ndeclarations which are not required.\n\nThe gfs2_quota_lvb structure has now had endianess annotations added\nto it. Also quota.c has been updated so that we now store the\nlvb data locally in endian independant format to avoid needing\na structure in host endianess too. As a result the endianess\nconversions are done as required at various points and thus the\nconversion routines in lvb.[ch] are no longer required. I\u0027ve\nmoved the one remaining constant in lvb.h thats used into lm.h\nand removed the unused lvb.[ch].\n\nI have not changed the HIF_ constants. That is left to a later patch\nwhich I hope will unify the gh_flags and gh_iflags fields of the\nstruct gfs2_holder.\n\nCc: Jan Engelhardt \u003cjengelh@linux01.gwdg.de\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

      "message": "[GFS2] Fix unlinked file handling\n\nThis patch fixes the way we have been dealing with unlinked,\nbut still open files. It removes all limits (other than memory\nfor inodes, as per every other filesystem) on numbers of these\nwhich we can support on GFS2. It also means that (like other\nfs) its the responsibility of the last process to close the file\nto deallocate the storage, rather than the person who did the\nunlinking. Note that with GFS2, those two events might take place\non different nodes.\n\nAlso there are a number of other changes:\n\n o We use the Linux inode subsystem as it was intended to be\nused, wrt allocating GFS2 inodes\n o The Linux inode cache is now the point which we use for\nlocal enforcement of only holding one copy of the inode in\ncore at once (previous to this we used the glock layer).\n o We no longer use the unlinked \"special\" file. We just ignore it\ncompletely. This makes unlinking more efficient.\n o We now use the 4th block allocation state. The previously unused\nstate is used to track unlinked but still open inodes.\n o gfs2_inoded is no longer needed\n o Several fields are now no longer needed (and removed) from the in\ncore struct gfs2_inode\n o Several fields are no longer needed (and removed) from the in core\nsuperblock\n\nThere are a number of future possible optimisations and clean ups\nwhich have been made possible by this patch.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"
