Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */

This contains various fixes for this cycle:

* Revert the hfs{plus} deprecation warning that's also included in this
  pull request. The commit introducing the deprecation warning resides
  rather early in this branch. So simply dropping it would've rebased
  all other commits which I decided to avoid. Hence the revert in the
  same branch.

* Switch CONFIG_SYSFS_SYCALL default to n and decouple from CONFIG_EXPERT.

* Fix an audit bug caused by changes to our kernel path lookup
  helpers this cycle. Audit needs the parent path even if the dentry it
  tried to look up is negative.

* Ensure that the kernel path lookup helpers leave the passed in path
  argument clean when they return an error. This is consistent with all
  our other helpers.

* Ensure that vfs_getattr_nosec() calls bdev_statx() so the relevant
  information is available to kernel consumers as well.

* Don't set a timer and call schedule() if the timer will expire
  immediately in epoll.

* Make netfs lookup tables with __nonstring.

/* Testing */
