From: Marco Stornelli <redacted> Remove lock and unlock super operation. Signed-off-by: Marco Stornelli <redacted>Acked-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>Are you sure? It used to be that exofs_sync_fs() could be called concurrently. What about two "bash -c sync" calls or a sync and an unmount in parallel. anything protecting that? If so then sure, but please let me test first. Boaz .
Yes Boaz, I agree, it's the reason I asked for a comments for exofs and hpfs. The only reason to have a lock here is to serialize operations in parallel on the same super block. Marco
