1 ext4: address a benign compiler warning
3 From: Patrick Palka <patrick@parcs.ath.cx>
5 When !defined(CONFIG_EXT4_DEBUG), mb_debug() should be defined as a
6 no_printk() statement instead of an empty statement in order to suppress
7 the following compiler warning:
9 fs/ext4/mballoc.c: In function ‘ext4_mb_cleanup_pa’:
10 fs/ext4/mballoc.c:2659:47: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
11 mb_debug(1, "mballoc: %u PAs left\n", count);
