In the current jbd code, if a buffer on BJ_SyncData list is dirty and not locked, the buffer is refiled to BJ_Locked list, submitted to the IO and waited for IO completion. But the fsstress test showed the case that when a buffer was already submitted to the IO just before the buffer_dirty(bh) check, the buffer was not waited for IO completion. Following patch solves this problem. If it is assumed that a buffer is submitted to the IO before the buffer_dirty(bh) check and still being written to disk, this buffer is refiled to BJ_Locked list.

Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: NChristoph Lameter <clameter@sgi.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

When running several fsx's and other filesystem stress tests, we found cases where an unmapped buffer was still being sent to submit_bh by the ext3 dirty data journaling code. I saw this happen in two ways, both related to another thread doing a truncate which would unmap the buffer in question. Either we would get into journal_dirty_data with a bh which was already unmapped (although journal_dirty_data_fn had checked for this earlier, the state was not locked at that point), or it would get unmapped in the middle of journal_dirty_data when we dropped locks to call sync_dirty_buffer. By re-checking for mapped state after we've acquired the bh state lock, we should avoid these races. If we find a buffer which is no longer mapped, we essentially ignore it, because journal_unmap_buffer has already decided that this buffer can go away. I've also added tracepoints in these two cases, and made a couple other tracepoint changes that I found useful in debugging this.

A disk generated some I/O error, after it, I hitted J_ASSERT(transaction->t_updates > 0) in journal_stop(). It seems to happened on ext3_truncate() path from stack trace. Then, maybe the following case may trigger J_ASSERT(transaction->t_updates > 0). ext3_truncate() -> ext3_free_branches() -> ext3_journal_test_restart() -> ext3_journal_restart() -> journal_restart() transaction->t_updates--; /* another process aborted journal */ -> start_this_handle() returns -EROFS without transaction->t_updates++; -> ext3_journal_stop() -> journal_stop() J_ASSERT(transaction->t_updates > 0) If journal was aborted in middle of journal_restart(), ext3_truncate() may trigger J_ASSERT().

This is Eric Sesterhenn's jbd patch applied to jbd2. Commit: 41716c7c His words: Since commit d1807793 we dereference a NULL pointer. Coverity id #1432.
