Subject: [RFC PATCH 0/6] mm: Make more use of readahead_control [ver #2]
Date: Wed, 02 Sep 2020 16:44:17 +0100	[thread overview]
Message-ID: <159906145700.663183.3678164182141075453.stgit@warthog.procyon.org.uk> (raw)


Hi Willy,

Here's a set of patches to expand the use of the readahead_control struct,
essentially from do_sync_mmap_readahead() down.  It's on top of:

	http://git.infradead.org/users/willy/pagecache.git

Also pass file_ra_state into force_page_cache_readahead().

The bugfix for khugepaged.c is included as that code is further changed
here.

David
