From c2beff99eb03866df6fdbd3a93b08fd27eb8bf5c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 28 Nov 2022 17:24:35 -0800 Subject: xfs: add debug knob to slow down writeback for fun Add a new error injection knob so that we can arbitrarily slow down writeback to test for race conditions and aberrant reclaim behavior if the writeback mechanisms are slow to issue writeback. This will enable functional testing for the ifork sequence counters introduced in commit 745b3f76d1c8 ("xfs: maintain a sequence count for inode fork manipulations"). Signed-off-by: Darrick J.
