UBUNTU: SAUCE: shiftfs: use separate llseek method for directories
BugLink: https://bugs.launchpad.net/bugs/1824812
Give shiftfs it's own proper llseek method for directories.
Before this commit we used to rely on an llseek method that was
targeted for regular files for both directories and regular files.
However, the realfile's f_pos was not correctly handled when userspace
called lseek(2) on a shiftfs directory file. Give directories their
own llseek operation so that seeking on a directory file is properly
supported.
