From 6c7ef543df909dbdcd8cb24ef30627cba62a4e91 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 10 Aug 2021 09:29:55 -0600 Subject: fs: add kiocb alloc cache flag If this kiocb can safely use the polled bio allocation cache, then this flag must be set. Generally this can be set for polled IO, where we will not see IRQ completions of the request.
