fix: mm, tracing: kfree event name mismatching with provider kmem (v5.12)

Author: He Zhe
Author Date: 2021-04-19 09:09:28 UTC

fix: mm, tracing: kfree event name mismatching with provider kmem (v5.12)

a8bc8ae5c932 ("fix: mm, tracing: record slab name for kmem_cache_free() (v5.12)")
introduces the following call trace for kfree. This is caused by mismatch
between kfree event and its provider kmem.

This patch maps kfree to kmem_kfree.

lttng-modules v0.19-stable: setup_trace_write: Fix recursive locking

lttng-modules: ltt_trace_destroy calls ltt_lock_traces internally so
this non-recursive mutex must be first unlocked when executing error
handling code.
