Subject: __io_file_supports_nowait for regular files
Date: Thu, 21 Jul 2022 17:37:40 +0200 [thread overview]
Message-ID: <[email protected]> (raw)
Hi Jens,
is there any good reason __io_file_supports_nowait checks the
blk_queue_nowait flag for regular files? The FMODE_NOWAIT is set
for regular files that support nowait I/O, and should be all that
is needed. Even with a block device that does not nonblocking
I/O some thing like reading from the page cache can be done
non-blocking.
