to_mp() was first introduced with the following commit: 'commit 801cc4e17a34c ("xfs: debug mode forced buffered write failure")' But the user of to_mp() was removed by below commit: 'commit f8c47250ba46e ("xfs: convert drop_writes to use the errortag mechanism")' So kernel build with clang throws below warning message: fs/xfs/xfs_sysfs.c:72:1: warning: unused function 'to_mp' [-Wunused-function] to_mp(struct kobject *kobject) Hence to_mp() might be removed safely to get rid of warning message.
