From: Filipe Manana <fdmanana@suse.com> Fix a recent regression when doing concurrent direct IO writes and fsync using the same fd from multiple threads. This was reported recently by a couple users when using QEMU, as well as syzbot. The fix is the first patch in the series, the second one is just an improvement for some assertions. Details in the change logs of each patch.
