      "message": "[GFS2] assertion failure after writing to journaled file, umount\n\nThis patch passes all my nasty tests that were causing the code to\nfail under one circumstance or another.  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"
