Subject: [patch 3/3] swsusp: fix nr_copy_pages
Date: Tue, 26 Apr 2005 12:46:23 +0200 [thread overview]
Message-ID: <20050426104623.GA18028@elf.ucw.cz> (raw)
The following patch moves the recalculation of nr_copy_pages so that the
right number is used in the calculation of the size of memory and swap needed.
It prevents swsusp from attempting to suspend if there is not enough memory
and/or swap (which is unlikely anyway).
