cluster/afr: Avoid setting split-brain outside inode locks
RCA:
The bug is observed because the decision to mark
a file in split-brain is taken outside appropriate locks.
Lookup gathers xattrs outside any lock. The xattrs being
in split-brain in lookup should only be taken as a hint.
Appropriate inodelks should be taken before confirming
a split-brain. Self-heal confirms this at the moment.
Fix:
Self-heals are launched to inspect xattrs when the
data/metadata self-heal options are turned on.
Decision to set/reset split-brain flag is taken inside
appropriate locks.
Known Issue After fix:
If data/metadata self-heal is turned off, inspecting of
xattrs could not be performed so split-brain behavior
does not work correctly if the self-heal options are turned off.
This bug is handled only in upstream.
