ext4: address a benign compiler warning
When !defined(CONFIG_EXT4_DEBUG), mb_debug() should be defined as a no_printk() statement instead of an empty statement in order to suppress the following compiler warning: fs/ext4/mballoc.c: In function ‘ext4_mb_cleanup_pa’: fs/ext4/mballoc.c:2659:47: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] mb_debug(1, "mballoc: %u PAs left\n", count); Signed-off-by: Patrick Palka <patrick@parcs.ath.cx> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
