The patch titled
swapfile: swapon needs larger size type
has been removed from the -mm tree. Its filename was
swapfile-swapon-needs-larger-size-type.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: swapfile: swapon needs larger size type
From: Hugh Dickins <hugh@xxxxxxxxxxx>
sys_swapon()'s swapfilesize (better renamed swapfilepages) is declared as
an int, but should be an unsigned long like the maxpages it's compared
against: on 64-bit (with 4kB pages) a swapfile of 2^44 bytes was rejected
with "Swap area shorter than signature indicates".
