[PATCH 4/5] xfs: clean up refcount log intent item tracepoint callsites

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Pass the incore refcount intent structure to the tracepoints instead of
open-coding the argument passing.
