[PATCH -next v4 15/19] md/md-linear: cleanup linear_add()

From: Yu Kuai <hidden>
Date: 2023-10-10 07:24:43
Also in: lkml
Subsystem: software raid (multiple disks) support, the rest · Maintainers: Song Liu, Yu Kuai, Linus Torvalds

From: Yu Kuai <redacted>

Now that caller already suspend the array, there is no need to suspend
array in liner_add().

Note that mddev_suspend/resume() is not used anymore.
