Subject: failed open: No data available

Message-ID: <2nv9d47zt7.fsf@aldarion.sourceruckus.org> (raw)

I'm sporatically getting "no data available" as a reason to fail to
open files on an overlay mount.  Most obvious is during ln of backup
file during apt install.  Only seems to happen on copy_up from lower
layer.  Lower layer is squashfs (I've seen it happen with both the
default zlib and also zstd compression), upper is EXT4.

I've only bumped into this problem recently with 5.9+ kernels.  I'm
gonna go see if I can reproduce in some older kernels I still have
installed.

Anyone else reporting this?
