Subject: [PATCH] raid5-cache: add crc32c Kconfig dependency
Date: Tue, 03 Nov 2015 15:12:01 +0100 [thread overview]
Message-ID: <4308930.z8rrqMJU90@wuerfel> (raw)
The recent change of the raid5-cache code to use crc32c instead
of crc32 causes link errors when CONFIG_LIBCRC32C is disabled:
drivers/built-in.o: In function crc32c'
core.c:(.text+0x1c6060): undefined reference to `crc32c'
This adds an explicit 'select' statement like all other users
of this function do.
