dlm: fix invalid cluster name warning

2018-12-03T21:30:24+00:00

The warning added in commit 3b0e761ba83
  "dlm: print log message when cluster name is not set"

did not account for the fact that lockspaces created
from userland do not supply a cluster name, so bogus
warnings are printed every time a userland lockspace
is created.

dlm: NULL check before kmem_cache_destroy is not needed

2018-11-28T14:45:55+00:00

kmem_cache_destroy(NULL) is safe, so removes NULL check before
freeing the mem. This patch also fix ifnullfree.cocci warnings.

dlm: memory leaks on error path in dlm_user_request()

2018-11-15T15:57:22+00:00

According to comment in dlm_user_request() ua should be freed
in dlm_free_lkb() after successful attach to lkb.

However ua is attached to lkb not in set_lock_args() but later,
inside request_lock().

dlm: fix possible call to kfree() for non-initialized pointer

2018-11-13T17:41:09+00:00

Technically dlm_config_nodes() could return error and keep nodes
uninitialized. After that on the fail path of we'll call kfree()
for that uninitialized value.

The patch is simple - we should just initialize nodes with NULL.

dlm: Don't swamp the CPU with callbacks queued during recovery

2018-11-08T19:17:00+00:00

Before this patch, recovery would cause all callbacks to be delayed,
put on a queue, and afterward they were all queued to the callback
work queue. This patch does the same thing, but occasionally takes
a break after 25 of them so it won't swamp the CPU at the expense
of other RT processes like corosync.
