Log message:
Final patch for bugzilla 1904745 - there is a deadlock documented in the
bugzilla entry comment #26 that is messy to get around under current
GFS lock order rule. To compromise the issue, we will fail the rename
with the original error return code (-ENOENT), if the new ino has any
possibility to cause deadlock. This implies, if GFS ino number is
allocated via true random manner, we only reduce this error return
code by 25%.
