Subject: When we free the swap buffer, do Not munmap the buffer data.
X-Git-Tag: submit/devel/efl/20131022.203902~1143
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8c6d197480fb10a520c6bc7a05fd2abcbfcca64;p=platform%2Fupstream%2Fefl.git

When we free the swap buffer, do Not munmap the buffer data.

Buffer data (in this instance) is from the swapper (ie: the creation
of the swapper allocates & mmaps the data). As such, we should not
unmap it when we free buffer(s), just when we free the swapper.
