From 7f4d01f36a3ac16f539f0fd3839de5d58fa4940f Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 8 Aug 2017 18:21:52 -0700 Subject: xfs: add log item pinning error injection tag Add an error injection tag to force log items in the AIL to the pinned state. This option can be used by test infrastructure to induce head behind tail conditions. Specifically, this is intended to be used by xfstests to reproduce log recovery problems after failed/corrupted log writes overwrite the last good tail LSN in the log. When enabled, AIL push attempts see log items in the AIL in the pinned state. This stalls metadata writeback and thus prevents the current tail of the log from moving forward. When disabled, subsequent AIL pushes observe the log items in their appropriate state and filesystem operation continues as normal. Signed-off-by: Brian Foster Reviewed-by: Darrick J.

These reference counts dictate how aggressively certain buffers are reclaimed vs. others. While the reference counts implements priority across different buffer types, all buffers (other than uncached buffers) are typically cached for at least one reclaim cycle. We've had at least one bug recently that has been hidden by a released buffer sitting around in the LRU. Users hitting the problem were able to reproduce under enough memory pressure to cause aggressive reclaim in a particular window of time. To support future xfstests cases, add an error injection tag to hardcode the buffer reference count to zero. When enabled, this bypasses caching of associated buffers and facilitates test cases that depend on this behavior. Signed-off-by: Brian Foster Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
