Description

The zfs test mdb_001_pos can fail with the following errors:

13:34:20.94 SUCCESS: zpool scrub testpool
13:34:23.34 /opt/zfs-tests/tests/functional/mdb/mdb_001_pos[91]: ffffff0c6cba7000 ::zfs_blkstats -v: not found [No such file or directory]
13:34:23.34 ASSERTION: Verify that the ZFS mdb dcmds and walkers are working as expected.
13:34:23.34 NOTE: Verifying: '::abuf_find 1 2'
13:34:23.34 /opt/zfs-tests/tests/functional/mdb/mdb_001_pos[109]: : cannot open

The first error is trivial -- a missing '\' on the previous line (90).
The second error appears to be due to '$OUTFILE' not being set

This commit appears to be what broke the test:

    8021 ARC buf data scatter-ization
    8100 8021 seems to cause random BAD TRAP: type=d (#gp General protection)

However, in addition.. the ::abuf_find dcmd is broken

It appears DLPX-41846 fixes this, but was never upstreamed.
