[PATCH 0/2] ocfs2: validate active orphan slots during inode read

[ZhengYuan Huang <gality369@gmail.com>]

OCFS2 trusts active ordinary and append-DIO orphan slots read from dinodes.
A corrupted slot can therefore index osb_orphan_wipes or the slot-local
system-inode cache outside their allocations before the corruption is
reported.

Patch 1 validates the ordinary orphan slot used by inode wipe processing.
Patch 2 validates the append-DIO orphan slot used by DIO completion and
orphan recovery.  Both checks reject corrupt metadata at the existing inode
validation boundary.
