Subject: Btrfs: process all async extents on compressed write failure
X-Git-Url: http://git.hungrycats.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=709deb00a91d73dea126afd9920aaabc6e89d059;p=linux

Btrfs: process all async extents on compressed write failure

If we had an error when processing one of the async extents from our list,
we were not processing the remaining async extents, meaning we would leak
those async_extent structs, never release the pages with the compressed
data and never unlock and clear the dirty flag from the inode's pages (those
that correspond to the uncompressed content).
