      "message": "jbd2: fix error handling for checkpoint io\n\nWhen a checkpointing IO fails, current JBD2 code doesn\u0027t check the\nerror and continue journaling.  This means latest metadata can be\nlost from both the journal and filesystem.\n\nThis patch leaves the failed metadata blocks in the journal space\nand aborts journaling in the case of jbd2_log_do_checkpoint().\nTo achieve this, we need to do:\n\n1. don\u0027t remove the failed buffer from the checkpoint list where in\n   the case of __try_to_free_cp_buf() because it may be released or\n   overwritten by a later transaction\n2. jbd2_log_do_checkpoint() is the last chance, remove the failed\n   buffer from the checkpoint list and abort the journal\n3. when checkpointing fails, don\u0027t update the journal super block to\n   prevent the journaled contents from being cleaned.  For safety,\n   don\u0027t update j_tail and j_tail_sequence either\n4. when checkpointing fails, notify this error to the ext4 layer so\n   that ext4 don\u0027t clear the needs_recovery flag, otherwise the\n   journaled contents are ignored and cleaned in the recovery phase\n5. if the recovery fails, keep the needs_recovery flag\n6. prevent jbd2_cleanup_journal_tail() from being called between\n   __jbd2_journal_drop_transaction() and jbd2_journal_abort()\n   (a possible race issue between jbd2_log_do_checkpoint()s called by\n   jbd2_journal_flush() and __jbd2_log_wait_for_space())\n\nSigned-off-by: Hidehiro Kawai \u003chidehiro.kawai.ez@hitachi.com\u003e\nSigned-off-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\n\n"

Now commit record can be sent to disk without waiting for\ndescriptor blocks to be written to disk. This behavior is controlled\nusing JBD2_FEATURE_ASYNC_COMMIT flag. Older kernels/e2fsck should not be\nable to recover the journal with _ASYNC_COMMIT hence it is made\nincompat.\nThe commit header has been extended to hold the checksum along with the\ntype of the checksum.\n\nFor recovery in pass scan checksums are verified to ensure the sanity\nand completeness(in case of _ASYNC_COMMIT) of every transaction.\n\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Girish Shilamkar \u003cgirish@clusterfs.com\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\n"
