2021-11-04	9p: fix a bunch of checkpatch warnings	Dominique Martinet	1	-1/+1
	Sohaib Mohamed started a serie of tiny and incomplete checkpatch fixes but seemingly stopped halfway -- take over and do most of it. This is still missing net/9p/trans* and net/9p/protocol.c for a later time...

2011-10-24	fs/9p: Update zero-copy implementation in 9p	Aneesh Kumar K.V	1	-18/+3
	* remove lot of update to different data structure * add a seperate callback for zero copy request. * above makes non zero copy code path simpler * remove conditionalizing TREAD/TREADDIR/TWRITE in the zero copy path * Fix the dotu p9_check_errors with zero copy. Add sufficient doc around * Add support for both in and output buffers in zero copy callback * pin and unpin pages in the same context * use helpers instead of defining page offset and rest of page ourself * Fix mem leak in p9_check_errors * Remove 'E' and 'F' in p9pdu_vwritef Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

2011-03-15	[net/9p] Preparation and helper functions for zero copy	Venkateswararao Jujjuri (JV)	1	-0/+29
	This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.
