Subject: libqos: Split apart pc_alloc_init
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=af77f2cd7af1fa65a414c86767366bae95892e69;p=qemu.git

libqos: Split apart pc_alloc_init

Move the list-specific initialization over into
malloc.c, to keep all of the list implementation
details within the same file.

The allocation and freeing of these structures are
now both back within the same layer.
