Subject: annotate noio context
Date: Fri, 17 Jan 2025 08:44:06 +0100 [thread overview]
Message-ID: <20250117074442.256705-1-hch@lst.de> (raw)
Hi all,
based on the reports from lockdep annotating q_usage_count it became
clear that we need to do noio allocations in a lot more place. One
is when the block driver calls back into the file system as in the
loop driver, the other is anything done while a process has a queue
frozen.
