From cc260b66c4cd21a370b39f73c9034a420baf8f79 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 15 May 2024 16:12:33 +0800 Subject: [PATCH] f2fs: add support for FS_IOC_GETFSSYSFSPATH FS_IOC_GETFSSYSFSPATH ioctl expects sysfs sub-path of a filesystem, the format can be "$FSTYP/$SYSFS_IDENTIFIER" under /sys/fs, it can helps to standardizes exporting sysfs datas across filesystems. This patch wires up FS_IOC_GETFSSYSFSPATH for f2fs, it will output "f2fs/".
