[PATCH 1/7] xfs_scrub: flush stdout after printing to it

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Make sure we flush stdout after printf'ing to it, especially before we
start any operation that could take a while to complete.  Most of scrub
already does this, but we missed a couple of spots.
