Subject: Re: linux-next: Tree for July 20 (overlayfs)

Hi,

I have here a problem with linux-next (next-20110720) and
overlayfs-v10 (not the latest from GIT).

### OVERLAYFS
# Patches from mszeredi/vfs.git#overlayfs.v10 (up to commit
00b27467b181a27c808cef0d66860eba5f450b24)
# "overlay: overlay filesystem documentation"
# See also <http://lkml.org/lkml/2011/6/1/456>
# "[PATCH 0/7] overlay filesystem: request for inclusion"
+ overlayfs-v10/overlayfs-v10.patch

Documentation/filesystems/porting says:

[mandatory]
        ->permission(), generic_permission() and ->check_acl() have lost flags
argument; instead of passing IPERM_FLAG_RCU we add MAY_NOT_BLOCK into mask.
        generic_permission() has also lost the check_acl argument; if you want
non-NULL to be used for that inode, put it into ->i_op->check_acl.

I checked with other files below fs/ and changed accordingly.
So, I hope the attached patch is OK (untested, uncompiled)?

What's the status of OverlayFS anyway, will it be merged into v3.1?
