The revokeat(2) system call ensures that after successful revocation you can
only access an inode via a file descriptor that is obtained from a subsequent
open(2) call. The open(2) system call can be blocked by the caller with
chmod(2) and chown(2) prior to
Exporting drop_pagecache_sb to modules is somewhat risky because one cannot
sleep inside invalidate_mapping_pages. This could cause a lot of latency in
the pre-emption code. So don't export this symbol to minimize the risk that
others will use it.
Instead, unionfs will try to directly

This adds special handling for revoked shared memory mappings. We want to
raise SIGBUS if someone accesses a revoked mapping and return ENODEV if
somebody tries to remap one with mmap(2).

The revoke operation cannibalizes the revoked struct inode and removes it from
the inode cache thus forcing subsequent callers to look up the real inode.
Therefore we must make sure that while the revoke operation is in progress

Hello Professor Zadok,
Erez Zadok:
I believe that small VFS changes to help stackable file systems are
perfectly reasonable, and a good thing; and I'm working on such patches.
Conversely, I am very mindful of the VFS's complexity, so I also believe
that massive VFS changes are a bad thing; I
