[PATCH 4.4 0/3] Fix read-only issue with non-empty workdir

Hi,

This patch series fixes read-only issue when non-empty workdir occurred in overlayfs, the non-empty workdir could be easily reproduced in power-failure test during write operations.

These patches have passed basic test in unionmount-testsuite.

Antonio Murdaca (1): ovl: override creds with the ones from the superblock mounter

Miklos Szeredi (2): ovl: rename is_merge to is_lowest ovl: proper cleanup of workdir
