[Cluster-devel] [PATCH RESEND v5.19-rc3 15/20] fs: dlm: change -EINVAL recovery error to -EAGAIN

[Alexander Aring <aahringo@redhat.com>]

This patch changes a -EINVAL error for dlm_master_lookup() to -EAGAIN.
It is a critical error which should not happened, if it happens there
exists an issue. However we still track those issues inside the lock but
if they happen we try to run recovery again if those issues will get
resolved. If not recovery has a logic to fail this node after several
retries.
