Subject: [PATCHSET 0/2] kbuf fixes
Date: Tue, 28 Apr 2026 09:44:48 -0600 [thread overview]
Message-ID: <20260428154557.2150818-1-axboe@kernel.dk> (raw)
Hi,
First patch just kills an unused member in struct io_buffer_list,
and then patch 2 fixes up an issue with incrementally consumed
buffers where the application cannot inform the kernel of how much
space should be left before moving on to the next buffer. This can
cause spurious -EFAULT with multishot recvmsg, when the current
buffer falls below the limit needed for the headers.
