ok, any further bikeshedding better be along the lines of "this will cause a gaping security hole unless addressed" ;) changes since v2: - now using nak (0x15) ioctl range; documentation updated - new helpers for setting the sysfs name - sysfs name uuid now has a length field other notes: - fscrypt usage of s_uuid has justification, so we don't need to be concerned about exporting that (more) to userspace - i haven't updated btrfs for FS_IOC_SYSFS_NAME, less familiar with their code so they are cc'd ext4 may want this too?
