/*
 * CRC32C definitions for ext4l
 *
 * CRC32C (Castagnoli) uses polynomial 0x1EDC6F41 (bit-reflected: 0x82F63B78)
 * This is different from standard CRC32 (IEEE 802.3) which uses 0x04C11DB7.
 *
 * ext4l provides its own implementation to avoid conflicts with other
 * filesystems (e.g., btrfs) that have their own crc32c().
