Certainly the locking could be changed, but it would be nice to have a reason other than aesthetics. sysfs is not unique, we also do not grab the rwlock lock during any commands executed as part of probe. There are basically two locking regimes - stuff that is proven to by synchronous with probe/remove (sysfs, probe cmds) and everything else (kapi, cdev) Further, the current sysfs implementation is nice and sane: the file accesses cannot fail with ENODEV. That is a useful concrete property and I don't think we should change it without a good reason.
