Subject: ceph: enable async dirops by default
Git-commit: f7a67b463fb83a4b9b11ceaa8ec4950b8fb7f902
Patch-mainline: v5.16-rc1
References: jsc#SES-1880
Async dirops have been supported in mainline kernels for quite some time
now, and we've recently (as of June) started doing regular testing in
teuthology with '-o nowsync'. There were a few issues, but we've sorted
those out now.
Enable async dirops by default, and change /proc/mounts to show "wsync"
when they are disabled rather than "nowsync" when they are enabled.
