gfs2: Retries missing in gfs2_{rename,exchange}

Browse source

[ Upstream commit 11d763f0b0 ]

Fix a bug in gfs2's asynchronous glock handling for rename and exchange
operations.  The original async implementation from commit ad26967b9a
("gfs2: Use async glocks for rename") mentioned that retries were needed
but never implemented them, causing operations to fail with -ESTALE
instead of retrying on timeout.

Also makes the waiting interruptible.

In addition, the timeouts used were too high for situations in which
timing out is a rare but expected scenario.  Switch to shorter timeouts
with randomization and exponentional backoff.
