[PATCH 7/9] quota: Use the pre-processor to compile out quotactl_cmd_write when !CONFIG_BLOCK

From: Lee Jones
Date: Sat Nov 03 2012 - 18:03:44 EST


quotactl_cmd_write() is only ever invoked when BLOCK is configured. When
!CONFIG_BLOCK, the build warning below is displayed. Let's fix that.

fs/quota/quota.c:311:12: warning: âquotactl_cmd_writeâ defined but not used [-Wunused-function]
