[PATCH] dm log: Use ULL suffix for 64-bit constants

From: Geert Uytterhoeven
Date: Sat Apr 18 2015 - 18:07:34 EST


On 32-bit:

drivers/md/dm-log-writes.c: In function âlog_superâ:
drivers/md/dm-log-writes.c:323: warning: integer constant is too large for âlongâ type
drivers/md/dm-log-writes.c:323: warning: integer constant is too large for âlongâ type

drivers/md/dm-log-writes.c:323: warning: integer constant is too large for âlongâ type

Add a ULL suffix to WRITE_LOG_MAGIC to fix this.
Also add a ULL suffix to WRITE_LOG_VERSION as it's stored in a __le64
field.
