Subject: [PATCH] ceph: fix stale xattr when using read() on dir with '-o dirstat'
Date: Thu, 16 May 2024 19:00:21 +0200	[thread overview]
Message-ID: <> (raw)

Fixes stale recursive stats (rbytes, rentries, ...) being returned for
a directory after creating/deleting entries in subdirectories.

Now `getfattr` and `cat` return the same values for the attributes.
