[Ocfs2-devel] [PATCH 15/15] ocfs2: Add incompatible flag for extended attribute v2

[Tiger Yang]

Hi, Joel,

Why we want RO_COMPAT feature with xattr support?
If we make it RO_COMPAT, this means we could only support set xattr in a 
read only ocfs2. But sys_setxattr() need mount writable, so we couldn't 
set xattr at all.

Thanks,
tiger
