Subject: [RFC PATCH 0/3] vfs, overlayfs: Fix syncfs() to return error
Date: Wed, 16 Dec 2020 18:31:46 -0500	[thread overview]
Message-ID: <20201216233149.39025-1-vgoyal@redhat.com> (raw)

Hi,

This is V2 of patches which tries to fix syncfs() for overlayfs to
return error code when sync_filesystem(upper_sb) returns error or
there are writeback errors on upper_sb.

I posted V1 of patch here.

https://lore.kernel.org/linux-fsdevel/20201216143802.GA10550@redhat.com/

This is just compile tested patch series. Trying to get early feedback
to figure out what direction to move in to fix this issue. 

Thanks
Vivek
