jbd2: flush filesystem device before updating tail sequence

2025-01-17T12:40:33Z

[ Upstream commit a0851ea9cd555c333795b85ddd908898b937c4e1 ] When committing transaction in jbd2_journal_commit_transaction(), the disk caches for the filesystem device should be flushed before updating the journal tail sequence. However, this step is missed if the journal is not located on the filesystem device. As a result, the filesystem may become inconsistent following a power failure or system crash. Fix it by ensuring that the filesystem device is flushed appropriately.

jbd2: increase IO priority for writing revoke records

2025-01-17T12:40:33Z

[ Upstream commit ac1e21bd8c883aeac2f1835fc93b39c1e6838b35 ] Commit '6a3afb6ac6df ("jbd2: increase the journal IO's priority")' increases the priority of journal I/O by marking I/O with the JBD2_JOURNAL_REQ_FLAGS. However, that commit missed the revoke buffers, so also addresses that kind of I/Os.

It's more intuitive to use jh_in->b_frozen_data directly instead of done_copy_out variable. Simply remove unneeded done_copy_out variable and use b_frozen_data instead.
