      "message": "[GFS2] Clean up inode number handling\n\nThis patch cleans up the inode number handling code. The main difference\nis that instead of looking up the inodes using a struct gfs2_inum_host\nwe now use just the no_addr member of this structure. The tests relating\nto no_formal_ino can then be done by the calling code. This has\nadvantages in that we want to do different things in different code\npaths if the no_formal_ino doesn\u0027t match. In the NFS patch we want to\nreturn -ESTALE, but in the -\u003elookup() path, its a bug in the fs if the\nno_formal_ino doesn\u0027t match and thus we can withdraw in this case.\n\nIn order to later fix bz #201012, we need to be able to look up an inode\nwithout knowing no_formal_ino, as the only information that is known to\nus is the on-disk location of the inode in question.\n\nThis patch will also help us to fix bz #236099 at a later date by\ncleaning up a lot of the code in that area.\n\nThere are no user visible changes as a result of this patch and there\nare no changes to the on-disk format either.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

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"

Fixes for the various bugs will be\nforthcoming shortly.\n\nThis patch removes the special data format which has been used\nup till now for journaled data files. Directories still retain the\nold format so that they will remain on disk compatible with earlier\nreleases. As a result you can now do the following with journaled\ndata files:\n\n 1) mmap them\n 2) export them over NFS\n 3) convert to/from normal files whenever you want to (the zero length\n    restriction is gone)\n\nIn addition the level at which GFS\u0027 locking is done has changed for all\nfiles (since they all now use the page cache) such that the locking is\ndone at the page cache level rather than the level of the fs operations.\nThis should mean that things like loopback mounts and other things which\ntouch the page cache directly should now work.\n\nCurrent known issues:\n\n 1. There is a lock mode inversion problem related to the resource\n    group hold function which needs to be resolved.\n 2. Any significant amount of I/O causes an oops with an offset of hex 320\n    (NULL pointer dereference) which appears to be related to a journaled data\n    buffer appearing on a list where it shouldn\u0027t be.\n 3. Direct I/O writes are disabled for the time being (will reappear later)\n 4. There is probably a deadlock between the page lock and GFS\u0027 locks under\n    certain combinations of mmap and fs operation I/O.\n 5. Issue relating to ref counting on internally used inodes causes a hang\n    on umount (discovered before this patch, and not fixed by it)\n 6. One part of the directory metadata is different from GFS1 and will need\n    to be resolved before next release.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"
