[PATCH v3 0/2] ext4: fix fast commit inode enqueueing during a full journal commit

[Luis Henriques (SUSE)]

Hi!

Here's v3 of this fix to the fast commit enqueuing bug triggered by fstest
generic/047.  This version simplifies the previous patch version by re-using
the i_sync_tid field in struct ext4_inode_info instead of adding a new one.

The extra patch includes a few extra fixes to the tid_t type handling.  Jan
brought to my attention the fact that this sequence number may wrap, and I
quickly found a few places in the code where the tid_geq() and tid_gt()
helpers had to be used.

Again, please note that this fix requires [1] to be applied too.
