X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b6b5bce3571e496504a89ee575d32101e0a98b93;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] swsusp: Fix swap_type_of

There is a bug in mm/swapfile.c#swap_type_of() that makes swsusp only be
able to use the first active swap partition as the resume device.  Fix it.
