Subject: [RFC/RFT] multi-layer support for overlay filesystem
Date: Thu, 20 Nov 2014 18:03:13 +0100 [thread overview]
Message-ID: <20141120170313.GC3596@tucsk> (raw)
Here's the latest patchset to support multiple read-only layers for overlayfs.
Diffstat is against overlayfs-current branch.
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-next
I hope to have this included in 3.19.
Please review and test (I can post the full patchset if someone wants that).
Thanks,
Miklos
