      "message": "JBD2:  Clear buffer_ordered flag for barried IO request on success\n\nIn JBD2 jbd2_journal_write_commit_record(), clear the buffer_ordered\nflag for the bh after barried IO has succeed. This prevents later, if\nthe same buffer head were submitted to the underlying device, which has\nbeen reconfigured to not support barrier request, the JBD2 commit code\ncould treat it as a normal IO (without barrier).\n\nThis is a port from JBD/ext3 fix from Neil Brown.\n\nMore details from Neil:\n\nSome devices - notably dm and md - can change their behaviour in\nresponse to BIO_RW_BARRIER requests.  They might start out accepting\nsuch requests but on reconfiguration, they find out that they cannot\nany more. JBD2 deal with this by always testing if BIO_RW_BARRIER\nrequests fail with EOPNOTSUPP, and retrying the write\nrequests without the barrier (probably after waiting for any pending\nwrites to complete).\n\nHowever there is a bug in the handling this in JBD2 for ext4 .\n\nWhen ext4/JBD2 to submit a BIO_RW_BARRIER request,\nit sets the buffer_ordered flag on the buffer head.\nIf the request completes successfully, the flag STAYS SET.\n\nOther code might then write the same buffer_head after the device has\nbeen reconfigured to not accept barriers.  This write will then fail,\nbut the \"other code\" is not ready to handle EOPNOTSUPP errors and the\nerror will be treated as fatal.\n\nCc:  Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n"

The locking there is subtle though (as\neverywhere in JBD ;().  We use j_list_lock to protect the check and a\nsubsequent call to __journal_drop_transaction() and do the same in the end\nof journal_commit_transaction() which is the only place where a transaction\ncan get to T_FINISHED state.\n\nProbably I\u0027m too paranoid here and such locking is not really necessary -\ncheckpoint lists are processed only from log_do_checkpoint() where a\ntransaction must be already committed to be processed or from\n__journal_clean_checkpoint_list() where kjournald itself calls it and thus\ntransaction cannot change state either.

Thus\nthe compile warning occurs.\n\nThought about changing the jbd2_journal_enable_debug data type back to\nint, but can\u0027t, because the jbd2-debug is moved to debug fs, where\ncalling debugfs_create_u8() to create the debugfs entry needs the value\nto be u8 type.\n\nEven if we changed the data type back to int, the code is still buggy,\nkernel should not print jbd2 debug message if the\njbd2_journal_enable_debug is set to 0. But this is not the case.\n\nThe fix is change the level of debugging to 1. The same should fixed in\next3/JBD, but currently ext3 jbd-debug via /proc fs is broken, so we\nprobably should fix it all together.\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Jeff Garzik \u003cjeff@garzik.org\u003e\nCc: Theodore Tso \u003ctytso@mit.edu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

If we find a buffer which is no longer mapped,\nwe essentially ignore it, because journal_unmap_buffer has already decided\nthat this buffer can go away.\n\nI\u0027ve also added tracepoints in these two cases, and made a couple other\ntracepoint changes that I found useful in debugging this.\n\nSigned-off-by: Eric Sandeen \u003cesandeen@redhat.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
