[PATCH linux-next] selinux: avc: use sysfs_emit() instead of scnprintf()

From: xie.ludan
Date: Sat Mar 15 2025 - 02:12:26 EST


From: XieLudan <xie.ludan@xxxxxxxxxx>


Follow the advice in Documentation/filesystems/sysfs.rst:

show() should only use sysfs_emit() or sysfs_emit_at() when formatting

the value to be returned to user space.
