Thus, relax the checking in fs/ntfs/super.c::is_boot_sector_ntfs() to
only emit a warning when the checksum is incorrect rather than
refusing the mount. Thanks to Bernd Casimir for pointing this
problem out.

and handle the case where an attribute is converted from resident
to non-resident by a concurrent file write.
- Reorder some operations when converting an attribute from resident
to non-resident (fs/ntfs/attrib.c) so it is safe wrt concurrent
->readpage and ->writepage.

- Rename ntfs_find_vcn_nolock() to ntfs_attr_find_vcn_nolock().

This allows us to map runlist fragments with the runlist lock already
held without having to drop and reacquire it around the call. Adapt
all callers.

runlist. This allows us to find runlist elements with the runlist
lock already held without having to drop and reacquire it around the

This patch includes feedback from Andrew and Christoph. Thanks for
taking time to review.
Use of empty_zero_page was eliminated to fix compilation for architectures
that don't have it.
This patch removes setting pages up-to-date in ext2_get_xip_page and all
bug checks to verify that the page is indeed up to date. Setting the page
state on mapping to userland is bogus. None of the code patchs involved
with these pages in mm cares about the page state.
