Message-ID: <887371.1737149392@warthog.procyon.org.uk> (raw)

Note that netfslib provides some tracepoints that you can use to try and
illuminate what's going on there.

echo 1 > /sys/kernel/debug/tracing/events/netfs/netfs_read/enable
echo 1 > /sys/kernel/debug/tracing/events/netfs/netfs_rreq/enable
echo 1 > /sys/kernel/debug/tracing/events/netfs/netfs_sreq/enable
echo 1 > /sys/kernel/debug/tracing/events/netfs/netfs_failure/enable

for starters.

David
