Dave Hansen 18f335aff8 [PATCH] r/o bind mounts: elevate write count for xattr_permission() callers ...

This basically audits the callers of xattr_permission(), which calls
permission() and can perform writes to the filesystem.

[AV: add missing parts - removexattr() and nfsd posix acls, plug for a leak
