d750c42ac2 ocfs2: add feature document for online file check
This document will describe OCFS2 online file check feature.  OCFS2 is
often used in high-availaibility systems.  However, OCFS2 usually
converts the filesystem to read-only when encounters an error.  This may
not be necessary, since turning the filesystem read-only would affect
other running processes as well, decreasing availability.

Then, a mount option (errors=continue) is introduced, which would return
the -EIO errno to the calling process and terminate furhter processing
so that the filesystem is not corrupted further.  The filesystem is not
converted to read-only, and the problematic file's inode number is
reported in the kernel log.  The user can try to check/fix this file via
online filecheck feature.
