[PATCH 5.4 05/17] xfs: add missing assert in xfs_fsmap_owner_from_rmap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Darrick J. Wong" <darrick.wong@xxxxxxxxxx>

commit 110f09cb705af8c53f2a457baf771d2935ed62d4 upstream.

The fsmap handler shouldn't fail silently if the rmap code ever feeds it
a special owner number that isn't known to the fsmap handler.
