Making common_lsm_audit() non-blocking; we don't really need to grab/drop
dentry in there - rcu_read_lock() is enough. There's a couple of followups
using that to simplify the logics in selinux, but those hadn't soaked in -next
yet, so they'll have to go in next window.
The following changes since commit d36a1dd9f77ae1e72da48f4123ed35627848507d:
dump_common_audit_data(): fix racy accesses to ->d_name (2021-01-16 15:11:35 -0500)
