9p: Small cleanup in

2011-05-25T13:46:38Z

There are two small cleanups in this patch: - p9_errstr2errno was declared twice - remove one declaration. - A uint8_t type was mixed in, change it to u8 to match with the rest of the type names and remove dependency.

9p: revert tsyncfs related changes

2011-04-15T20:26:14Z

Now that we use write_inode to flush server cache related to fid, we don't need tsyncfs either fort dotl or dotu protocols. For dotu this helps to do a more efficient server flush. Signed-off-by: Aneesh Kumar K.V Signed-off-by: Venkateswararao Jujjuri Signed-off-by: Eric Van Hensbergen

[net/9p] Small non-IO PDUs for zero-copy supporting transports.

2011-03-15T14:57:36Z

If a transport prefers payload to be sent separate from the PDU (P9_TRANS_PREF_PAYLOAD_SEP), there is no need to allocate msize PDU buffers(struct p9_fcall). This patch allocates only upto 4k buffers for this kind of transports and there won't be any change to the legacy transports. Hence, this patch on top of zero copy changes allows user to specify higher msizes through the mount option without hogging the kernel heap.

[net/9p] Add preferences to transport layer.

2011-03-15T14:57:35Z

This patch adds preferences field to the p9_trans_module. Through this, now transport layer can express its preference about the payload. i.e if payload neds to be part of the PDU or it prefers it to be sent sepearetly so that the transport layer can handle it in a better way.

[net/9p] Preparation and helper functions for zero copy

2011-03-15T14:57:34Z

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.

9p: Add datasync to client side TFSYNC/RFSYNC for dotl

2010-10-28T14:08:49Z

SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.
