Subject: Re: [PATCH] splice: Fix filemap of a blockdev
Date: Wed, 19 Apr 2023 14:01:20 +0100	[thread overview]
Message-ID: <1842478.1681909280@warthog.procyon.org.uk> (raw)
In-Reply-To: <168190833944.417103.14222689199936898089.b4-ty@kernel.dk>

Note that this shouldn't affect direct_splice_read() as that doesn't look at
the size of the file, but rather just keeps reading from it until the
requested amount is read, the pipe is full or ->read_iter() indicates EOF by
returning 0 (so it could work for copy-splicing from a pipe/socket/chardev
too).
