This patch extends that to mapping of extents when an\nallocation has been requested. In that case we try to allocate as many\nblocks as are requested, but we might return fewer in case there is\nsomething preventing us from returning the complete amount (e.g. an\nalready allocated block is in the way).\n\nCurrently the only code path which can actually request multiple data\nblocks in a single bmap call is the page_mkwrite path and even then it\nonly happens if there are multiple blocks per page. What this patch does\ndo however, is merge the allocation requests for metadata (growing the\nmetadata tree in either height or depth) with the allocation of the data\nblocks in the case that both are needed. This results in lower overheads\neven in the single block allocation case.\n\nThe one thing which we can\u0027t handle here at the moment is unstuffing. I\nwould like to be able to do that, but the problem which arises is that\nin order to unstuff one has to get a locked page from the page cache\nwhich results in locking problems in the (usual) case that the caller is\nholding the page lock on the page it wishes to map. So that case will\nhave to be addressed in future patches.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

Also in the case that the\ntree does need some extra height, we start from the current height rather from\nzero when we work out what the new height ought to be.\n\nIn addition the di_height field is moved into the inode proper and reduced\nin size to a u8 since the value must be between 0 and GFS2_MAX_META_HEIGHT (10).\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

Also those _host structures which are not required any more\nare removed entirely (which is the eventual plan for all of them).\n\nThe conversion routines from ondisk.c are also moved into the places\nwhere they are actually used, which for almost every one, was just one\nsingle place, so all those are now static functions. This also cleans up\nthe end of gfs2_ondisk.h which no longer needs the #ifdef __KERNEL__.\n\nThe net result is a reduction of about 100 lines of code, many functions\nnow marked static plus the bug fixes as mentioned above. For good\nmeasure I ran the code through sparse after making these changes to\ncheck that there are no warnings generated.\n\nThis fixes Red Hat bz #239686\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

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"

Updated the directory code to use the new\n\u0026 improved version of gfs2_meta_ra() which now returns the first block\nthat was being read. Previously it was releasing it requiring following\ncode to grab the block again at each point it was called.\n\nAlso turned off readahead on directory lookups since we are reading a\nhash table, and therefore reading the entries in order is very\nunlikely. Readahead is still used for all other calls to the\ndirectory reading function (e.g. when growing the hash table).\n\nRemoved the DIO_START constant. Everywhere this was used, it was\nused to unconditionally start i/o aside from a couple of places, so\nI\u0027ve removed it and made the couple of exceptions to this rule into\nseparate functions.\n\nAlso hunted through the other DIO flags and removed them as arguments\nfrom functions which were always called with the same combination of\narguments.\n\nUpdated gfs2_meta_indirect_buffer to be a bit more efficient and\nhopefully also be a bit easier to read.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

      "message": "[GFS2] Map multiple blocks at once where possible\n\nThis is a tidy up of the GFS2 bmap code. The main change is that the\nbh is passed to gfs2_block_map allowing the flags to be set directly\nrather than having to repeat that code several times in ops_address.c.\n\nAt the same time, the extent mapping code from gfs2_extent_map has\nbeen moved into gfs2_block_map. This allows all calls to gfs2_block_map\nto map extents in the case that no allocation is taking place. As a\nresult reads and non-allocating writes should be faster. A quick test\nwith postmark appears to support this.\n\nThere is a limit on the number of blocks mapped in a single bmap\ncall in that it will only ever map blocks which are pointed to\nfrom a single pointer block. So in other words, it will never try\nto do additional i/o in order to satisfy read-ahead. The maximum\nnumber of blocks is thus somewhat less than 512 (the GFS2 4k block\nsize minus the header divided by sizeof(u64)). I\u0027ve further limited\nthe mapping of \"normal\" blocks to 32 blocks (to avoid extra work)\nsince readpages() will currently read a maximum of 32 blocks ahead (128k).\n\nSome further work will probably be needed to set a suitable value\nfor DIO as well, but for now thats left at the maximum 512 (see\nops_address.c:gfs2_get_block_direct).\n\nThere is probably a lot more that can be done to improve bmap for GFS2,\nbut this is a good first step.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

      "message": "[GFS2] Reverse block order in build_height\n\nThe original code ordered the blocks allocated in the build_height\nroutine backwards causing excessive disk seeks during a read of the\nmetadata. This patch reverses the order to try and reduce disk seeks.\n\nExample: A five level metadata tree, I \u003d Inode, P \u003d Pointers, D \u003d Data\n\nYou need to read the blocks in the order:\n\nI P5 P4 P3 P2 P1 D\n\nin order to read a single data block. The new code now orders the blocks\nin this way. The old code used to order them as:\n\nI P1 P2 P3 P4 P5 D\n\nrequiring two extra seeks on average. Note that for files which are\ngrown by gradual extension rather than by truncate or by llseek/write\nat a large offset, this doesn\u0027t apply. In the case of writing to a\nfile linearly, this routine will only be called upon to extend the\nheight of the tree by one block at a time, so the ordering is\ndetermined by when its called rather than by the internals of the\nroutine itself. Optimising that part of the ordering is a much\nharder problem.\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"
