From: Filipe David Borba Manana Date: Wed, 29 Jan 2014 21:06:04 +0000 (+0000) Subject: Btrfs: use btrfs_crc32c everywhere instead of libcrc32c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b947aff1599afbbd2ec07ada87b05af0f94cf10;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Btrfs: use btrfs_crc32c everywhere instead of libcrc32c After the commit titled "Btrfs: fix btrfs boot when compiled as built-in", LIBCRC32C requirement was removed from btrfs' Kconfig. This made it not possible to build a kernel with btrfs enabled (either as module or built-in) if libcrc32c is not enabled as well. So just replace all uses of libcrc32c with the equivalent function in btrfs hash.h - btrfs_crc32c.
