Is it possible to have a race between sysfs and syspend/resume trying
to update the auto_hibern8?
Only user-space software should write into sysfs. Kernel code should
not do this. User-space code is paused before the block driver suspend
callbacks are invoked and resuming block devices completes before
user space software is resumed. I don't think that sysfs writes can
race with suspend or resume callbacks.
Thank you for the explanation.
