Subject: [PATCH] xfs: expose no-op xfs_put_perag()

Hi David,

Inline function xfs_put_perag() in fs/xfs/xfs_mount.h is a no-op.

This patch converts it to no-op macro.

As a result, gcc will emit warning about unused variables,
parameters and so on not in this function, but in its callers,
which is more useful.

This patch, together with previous ones, has already resulted
in more unused params discovered and warned about by gcc.

There is no object code size difference from this change.

Compile tested only.
