Re: [PATCH 4/5] fscache: netfs function for cleanup post readpages

I just wanted to follow up on this patch (and number 5) in the series. The backtrace I posted originally is not correct backtrace from this particular issue. The new one I attached at the bottom of this email is the right one. The backtrace I posted is a that only Ceph experiences in ceph_readpages

[PATCH 4/5] fscache: netfs function for cleanup post readpages

Currently the fscache code expect the netfs to call fscache_readpages_or_alloc inside the aops readpages callback. It marks all the pages in the list provided by readahead with PgPrivate2. In the cases that the netfs fails to read all the pages (which is legal) it ends up returning to the readahead
