-Subject: [PATCH 4/6] vhost: replace ffsl with ctzl
-
-Avoid using the GNU extesion ffsl which is not implemented in musl libc.
-
-The atomic_xchg() means we know that vhost_log_chunk_t will never be
-larger than the 'long' type, so ctzl() is always sufficient.
-
-See also commit fbeadf50 (bitops: unify bitops_ffsl with the one in
-host-utils.h, call it bitops_ctzl) on why ctzl should be used instead
-of ffsl.
