      "message": "[PATCH] jbd2: journal_dirty_data re-check for unmapped buffers\n\nWhen running several fsx\u0027s and other filesystem stress tests, we found\ncases where an unmapped buffer was still being sent to submit_bh by the\next3 dirty data journaling code.\n\nI saw this happen in two ways, both related to another thread doing a\ntruncate which would unmap the buffer in question.\n\nEither we would get into journal_dirty_data with a bh which was already\nunmapped (although journal_dirty_data_fn had checked for this earlier, the\nstate was not locked at that point), or it would get unmapped in the middle\nof journal_dirty_data when we dropped locks to call sync_dirty_buffer.\n\nBy re-checking for mapped state after we\u0027ve acquired the bh state lock, we\nshould avoid these races.  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"
