Here is a complete summary\nof all changes from today\u0027s git tree, in order of appearance:\n\n1. There are now separate variables for metadata buffer accounting.\n2. Variable sd_log_num_hdrs is no longer needed, since the header\n accounting is taken care of by the reserve/refund sequence.\n3. Fixed a tiny grammatical problem in a comment.\n4. Added a new function \"calc_reserved\" to calculate the reserved\n log space. This isn\u0027t entirely necessary, but it has two benefits:\n First, it simplifies the gfs2_log_refund function greatly.\n Second, it allows for easier debugging because I could sprinkle the\n code with calls to this function to make sure the accounting is\n proper (by adding asserts and printks) at strategic point of the code.\n5. In log_pull_tail there apparently was a kludge to fix up the\n accounting based on a \"pull\" parameter. The buffer accounting is\n now done properly, so the kludge was removed.\n6. File sync operations were making a call to gfs2_log_flush that\n writes another journal header. Since that header was unplanned\n for (reserved) by the reserve/refund sequence, the free space had\n to be decremented so that when log_pull_tail gets called, the free\n space is be adjusted properly. (Did I hear you call that a kludge?\n well, maybe, but a lot more justifiable than the one I removed).\n7. In the gfs2_log_shutdown code, it optionally syncs the log by\n specifying the PULL parameter to log_write_header. I\u0027m not sure\n this is necessary anymore. It just seems to me there could be\n cases where shutdown is called while there are outstanding log\n buffers.\n8. In the (data)buf_lo_before_commit functions, I changed some offset\n values from being calculated on the fly to being constants.\tThat\n simplified some code and we might as well let the compiler do the\n calculation once rather than redoing those cycles at run time.\n9. This version has my rewritten databuf_lo_add function.\n This version is much more like its predecessor, buf_lo_add, which\n makes it easier to understand. Again, this might not be necessary,\n but it seems as if this one works as well as the previous one,\n maybe even better, so I decided to leave it in.\n10. In databuf_lo_before_commit, a previous data corruption problem\n was caused by going off the end of the buffer. The proper solution\n is to have the proper limit in place, rather than stopping earlier.\n (Thus my previous attempt to fix it is wrong).\n If you don\u0027t wrap the buffer, you\u0027re stopping too early and that\n causes more log buffer accounting problems.\n11. In lops.h there are two new (previously mentioned) constants for\n figuring out the data offset for the journal buffers.\n12. There are also two new functions, buf_limit and databuf_limit to\n calculate how many entries will fit in the buffer.\n13. In function gfs2_meta_wipe, it needs to distinguish between pinned\n metadata buffers and journaled data buffers for proper journal buffer\n accounting.\tIt can\u0027t use the JDATA gfs2_inode flag because it\u0027s\n sometimes passed the \"real\" inode and sometimes the \"metadata\n inode\" and the inode flags will be random bits in a metadata\n gfs2_inode.\tIt needs to base its decision on which was passed in.\n\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "2840501ac822c5bf712f67b4b02640e16e145a29", "tree": "6fe4bed0d7d80d324c5d39f7528668adb123311b", "parents": [ "c4201214cbf10636e2c1ab9131573f735b42c8d4" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jun 18 16:31:42 2007 +0100" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jul 09 08:23:45 2007 +0100" }, "message": "[GFS2] Use zero_user_page() in stuffed_readpage()\n\nAs suggested by Robert P.

This makes sense, since you haven\u0027t written anything to that\npart of the file yet. Unfortunately, gfs2_pin() checks to make sure that the\nbuffers are uptodate.

I\u0027m pretty confident with this fix, although it\u0027s not completely\nobvious that there is no problem with marking the buffers uptodate here.\n\nThe second issue is simply that you can try to pin a data buffer that is already\non the incore log, and thus, already pinned. This patch checks to see if this\nbuffer is already on the log, and exits databuf_lo_add() if it is, just like\nbuf_lo_add() does.\n\nThe third issue is that gfs2_log_flush() doesn\u0027t do it\u0027s block accounting\ncorrectly. Both metadata and journaled data are logged, but gfs2_log_flush()\nonly compares the number of metadata blocks with the number of blocks to commit\nto the ondisk journal.

The current patch does the statfs_change\ninside the gfs2_commit_write function, which keeps it under the\numbrella of the inode transaction.\n\nI can\u0027t call ri_update to re-read the rindex file during the\ntransaction because the transaction may have outstanding unwritten\nbuffers attached to the rgrps that would be otherwise blown away.\nSo instead, I created a new function, gfs2_ri_total, that will\nre-read the rindex file just to total the file system space\nfor the sake of the statfs_change. The ri_update will happen\nlater, when gfs2 realizes the version number has changed, as it\nhappened before my patch.\n\nSince the statfs_change is happening at write_commit time and there\nmay be multiple writes to the rindex file for one grow operation.\nSo one consequence of this restructuring is that instead of getting\none kernel message to indicate the change, you may see several.\nFor example, before when you did a gfs2_grow, you\u0027d get a single\nmessage like:\n\nGFS2: File system extended by 247876 blocks (968MB)\n\nNow you get something like:\n\nGFS2: File system extended by 207896 blocks (812MB)\nGFS2: File system extended by 39980 blocks (156MB)\n\nThis version has also been successfully run against the hours-long\n\"gfs2_fsck_hellfire\" test that does several gfs2_grow and gfs2_fsck\nwhile interjecting file system damage.

Unfortunately, it neglected to\nensure that the _second_ redzone, after the slab object, is aligned\ncorrectly. This caused illegal instruction faults on sparc32, which for\nsome reason not entirely clear to me are not trapped and fixed up.\n\nTwo things need to be done to fix this:\n - increase the object size, rounding up to alignof(long long) so\n that the second redzone can be aligned correctly.\n - If SLAB_STORE_USER is set but alignof(long long)\u003d\u003d8, allow a\n full 64 bits of space for the user word at the end of the buffer,\n even though we may not _use_ the whole 64 bits.\n\nThis patch should be a no-op on any 64-bit architecture or any 32-bit\narchitecture where alignof(long long) \u003d\u003d 4.
