Subject: [PATCH 0/3][V3] Delayed iput fixes
Date: Fri, 11 Jan 2019 10:21:00 -0500 [thread overview]
Message-ID: <20190111152103.17001-1-josef@toxicpanda.com> (raw)
v1->v2:
- only wakeup if the cleaner isn't currently doing work.
- re-arranged some stuff for running delayed iputs during flushint.
- removed the open code wakeup in the waitqueue patch.
-- Original message --
Here are some delayed iput fixes. Delayed iputs can hold reservations for a
while and there's no real good way to make sure they were gone for good, which
means we could early enospc when in reality if we had just waited for the iput
we would have had plenty of space. So fix this up by making us wait for delayed
iputs when deciding if we need to commit for enospc flushing, and then cleanup
and rework how we run delayed iputs to make it more straightforward to wait on
them and make sure we're all done using them. Thanks,
Josef
