Subject: [PATCH] kexec: export PG_swapbacked to VMCOREINFO
Date: Tue, 10 Apr 2018 16:13:45 +0200	[thread overview]
Message-ID: <> (raw)

Since commit 6326fec1122cde256bd2a8c63f2606e08e44ce1d PG_swapcache
is an alias for PG_owner_priv_1, which may be also used for other
purposes. To know whether the bit indeed has the PG_swapcache
meaning, it is necessary to check PG_swapbacked, hence this bit must
be exported.
