Derek McGowan	5a1b557281	Skip overlay2 diff tests when using naivediff ... Naivediff fails when layers are created directly on top of each other. Other graphdrivers which use naivediff already skip these tests. Until naivediff is fixed, skip with overlay2 when running tests on a kernel which causes naivediff fallback. Fix applydiff to never use the naivediff size when not applying changes with naivediff. Signed-off-by: Derek McGowan <derek@mcgstyle.net> (github: dmcgowan)	2016-11-10 13:52:22 -08:00
Derek McGowan	23e5c94cfb	Add separate overlay2 driver ... Adds a new overlay driver which uses multiple lower directories to create the union fs. Additionally it uses symlinks and relative mount paths to allow a depth of 128 and stay within the mount page size limit. Diffs and done directly over a single directory allowing diffs to be done efficiently and without the need fo the naive diff driver.
