[linux-next] configfs: set new file and directory owners

Commit Message

Vlad Dogaru May 7, 2015, 1:06 p.m. UTC

All new files and directories in configfs are owned by root, regardless
of the process which creates them.  Fix this by preserving filesystem
semantics and assigning the uid and gid of the current process to all
new items in configfs.
