Subject: [PATCH 0/2] Propagate overlay f_mode from underlying file
Date: Sun, 14 Jun 2020 16:09:37 +0300	[thread overview]
Message-ID: <20200614130939.7702-1-amir73il@gmail.com> (raw)

Miklos,

Following the discussions on hugetlbfs-overlayfs, I wanted to see
if we can do better to emulate the underlying file supported ops.

Those patches don't actually help the hugetlbfs issue at all and
I am not sure they improve anything, but I though it would be better
if you had a look to say if there is anything interesting we can
get from this.

Thanks,
Amir.
