Subject: mm/swap_state.c: remove the meaningless code comment
X-Git-Tag: v6.15-rc1~81^2~371
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e89c45c700e7d9ab4913ec98f1fe9f23d46c1397;p=thirdparty%2Fkernel%2Flinux.git

mm/swap_state.c: remove the meaningless code comment

Since commit 8d93b41c09d1 ("mm: Convert add_to_swap_cache to XArray"),
there's no returned _EEXIT, so the code comment doesn't make sense any
more.
