Subject: [PATCH] lib: memscan() fixlet
Date: Sun, 6 Jun 2021 01:19:28 +0300 [thread overview]
Message-ID: <YLv4cCf0t5UPdyK+@localhost.localdomain> (raw)
Generic version doesn't trucate second argument to char.
Older brother memchr() does as do s390, sparc and i386 assembly
versions.
Fortunately, no code passes c >= 256.
