Subject: sys_swapon: separate final enabling of the swapfile
X-Git-Tag: v2.6.39-rc1~290
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=40531542e2832419566c997af0808513f6f2815d;p=pandora-kernel.git

sys_swapon: separate final enabling of the swapfile

The block in sys_swapon which does the final adjustments to the
swap_info_struct and to swap_list is the same as the block which
re-inserts it again at sys_swapoff on failure of try_to_unuse(). Move
this code to a separate function, and use it both in sys_swapon and
sys_swapoff.
