Hey Linus,
/* Summary */
This contains a few small fixes for this merge window and the attempt to handle
the ntfs removal regression that was reported a little while ago:
* After the removal of the legacy ntfs driver we received reports about
regressions for some people that do mount "ntfs" explicitly and expect the
driver to be available. Since ntfs3 is a drop-in for legacy ntfs we alias
legacy ntfs to ntfs3 just like ext3 is aliased to ext4.
We also enforce legacy ntfs is always mounted read-only and give it custom
file operations to ensure that ioctl()'s can't be abused to perform write
operations.
* Fix an unbalanced module_get() in bdev_open().
* Two smaller fixes for the netfs work done earlier in this cycle.
* Fix the errno returned from the new FS_IOC_GETUUID and FS_IOC_GETFSSYSFSPATH
ioctls. Both commands just pull information out of the superblock so there's
no need to call into the actual ioctl handlers.
So instead of returning ENOIOCTLCMD to indicate to fallback we just return
ENOTTY directly avoiding that indirection.
