[PATCH v3 00/15] Introduce cached report zones

[Christoph Hellwig]

I just threw this into my xfstests setup, and it seems this version
is broken somehow.  Running on emulated ZNS devices with XFS I get
a lot of failures with warnings like this:

[   30.068652] XFS (nvme1n1): empty zone 1 has non-zero used counter (0x1).

[   49.316873] XFS (nvme0n1): empty zone 2 has non-zero used counter (0x10).

so it seems like it's not tracking WPs correctly, probably when using
zone append and unmount/remounting.
