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.

This causes\niput_final() to be called, which puts an inode into state I_FREEING at\ngeneric_delete_inode(). There no point between when iput_final() is called, and\nwhen I_FREEING is set where GFS2 could acquire any glocks. Once I_FREEING is\nset, no other process on that node can successfully look up that inode until\nthe delete finishes.\n\nprocess B locks the the resource group for the same inode in get_local_rgrp(),\nwhich is called by gfs2_inplace_reserve_i()\n\nprocess A tries to lock the resource group for the inode in\ngfs2_dinode_dealloc(), but it\u0027s already locked by process B\n\nprocess B waits in find_inode for the inode to have the I_FREEING state cleared.\n\nDeadlock.\n\nThis patch solves the problem by adding an alternative to gfs2_iget(),\ngfs2_iget_skip(), that simply skips any inodes that are in the I_FREEING\nstate.o The alternate test function is just like the original one, except that\nit fails if the inode is being freed, and sets a skipped flag.

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"

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"
