mm: use sysfs_emit for struct kobject * uses
Patch series "mm: Convert sysfs sprintf family to sysfs_emit", v2.
Use the new sysfs_emit family and not the sprintf family.
This patch (of 5):
Use the sysfs_emit function instead of the sprintf family.
Done with cocci script as in commit 3c6bff3cf988 ("RDMA: Convert sysfs
kobject * show functions to use sysfs_emit()")
