bcachefs: "Journal stuck" timeout now takes into account device latency 2025-01-21T23:32:05+00:00 Kent Overstreet kent.overstreet@linux.dev 2025-01-21T22:42:25+00:00 2c5d8a8347a8ea8c243245e2ed8d87dfbf9f54fb If a block device (e.g. your typical consumer SSD) is taking multiple seconds for IOs (typically flushes), we don't want to emit the "journal stuck" message prematurely. Also, make sure to drop the btree_trans srcu lock if we're blocking for more than a second. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> 
If a block device (e.g. your typical consumer SSD) is taking multiple
seconds for IOs (typically flushes), we don't want to emit the "journal
stuck" message prematurely.

Also, make sure to drop the btree_trans srcu lock if we're blocking for
more than a second.
