Subject: [PATCH] Add O_NONBLOCK support to FUSE
Date: Tue, 28 Feb 2006 21:29:44 -0500 [thread overview]
Message-ID: <20060301022944.GB9624@ccure.user-mode-linux.org> (raw)
This adds O_NONBLOCK support to FUSE.
I don't like duplicating the connected and list_empty tests in
fuse_dev_readv, but this seemed cleaner than adding the f_flags test
to request_wait.
