Hi,
this patch fixes some missing spin_unlock() that was missing in commit
dc52cd2eff4a ("fs: dlm: fix F_CANCELLK to cancel pending request").
Otherwise this patch series contains:
- introduce a new debugfs entry to dump all pending callbacks in the per
lkb callbacks queue.
- add plock char dev kernel tracepoints for debugging
- change things in parsing/processing dlm messages like only once
dereferencing the sequence number of dlm recovery and avoid an additional
spinlock later
- constify the dlm receive buffer, it should never be manipulated when
parsing it.
- small change in version detection to not use RCOM_NAMES messages
- change to create midcomms node when configfs gets the cluster
configuration
I try to prepare to switch the message processing from workqueue
context to softirq context. The patch "fs: dlm: create midcomms nodes
when configure" will remove creating midcomms nodes that create debugfs
entries from the message parsing context. The context for creating debugfs
entries is sleepable. The lifetime of a midcomms node is now similar like
lowcomms connection struct. Later we hopefully can merge the two hash
datastructures midcomms nodes and lowcomms connections into one.
