Hi all,
Today's linux-next merge of the akpm-current tree got a conflict in:
include/linux/pagemap.h
between commits:
13aecd8259dc ("mm: Implement readahead_control pageset expansion")
9a28f7e68602 ("netfs: Rename unlock_page_fscache() and wait_on_page_fscache()")
from the fscache tree and commits:
cd669a9cbd89 ("mm/filemap: add mapping_seek_hole_data")
34c37da5f411 ("mm/filemap: pass a sleep state to put_and_wait_on_page_locked")
from the akpm-current tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
