From 3e5a428b264eca8c7f1c261cffbe139538d7965f Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 3 Jul 2019 07:33:27 -0700 Subject: xfs: poll waiting for quotacheck Create a pwork destroy function that uses polling instead of uninterruptible sleep to wait for work items to finish so that we can touch the softlockup watchdog. IOWs, gross hack. Signed-off-by: Darrick J.
