2011-10-24fs/9p: Update zero-copy implementation in 9pAneesh Kumar K.V1-8/+2
* 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] Add preferences to transport layer.Venkateswararao Jujjuri (JV)1-0/+9
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.

2008-10-179p: make rpc code common and rework flush codeEric Van Hensbergen1-4/+4
This code moves the rpc function to the common client base, reorganizes the flush code to be more simple and stable, and makes the necessary adjustments to the underlying transports to adapt to the new structure. This reduces the overall amount of code duplication between the transports and should make adding new transports more straightforward. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: consolidate transport structureEric Van Hensbergen1-48/+7
Right now there is a transport module structure which provides per-transport type functions and data and a transport structure which contains per-instance public data as well as function pointers to instance specific functions. This patch moves public transport visible instance data to the client structure (which in some cases had duplicate data) and consolidates the functions into the transport module structure.

2008-09-249p: implement proper trans module refcounting and unregistrationTejun Heo1-2/+7
9p trans modules aren't refcounted nor were they unregistered properly. Fix it. * Add 9p_trans_module->owner and reference the module on each trans instance creation and put it on destruction. * Protect v9fs_trans_list with a spinlock. This isn't strictly necessary as the list is manipulated only during module loading / unloading but it's a good idea to make the API safe. * Unregister trans modules when the corresponding module is being unloaded. * While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().

2008-05-149p: fix error path during early mountEric Van Hensbergen1-1/+0
There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd transport separate from the core 9pnet code seemed like a good idea at the time, but in practice has caused more harm and confusion than good.

2008-05-149p: Documentation updatesEric Van Hensbergen1-0/+43
The kernel-doc comments of much of the 9p system have been in disarray since reorganization. This patch fixes those problems, adds additional documentation and a template book which collects the 9p information. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-02-069p: transport API reorganizationEric Van Hensbergen1-6/+5
This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step.

2008-02-069p: block-based virtio clientEric Van Hensbergen1-1/+1
This replaces the console-based virto client with a block-based client using a single request queue. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-02-069p: create transport rpc cut-thruEric Van Hensbergen1-0/+2
Add a new transport function which allows a cut-thru directly to the transport instead of processing request through the mux if the cut-thru exists. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-10-179p: fix bad kconfig cross-dependencyEric Van Hensbergen1-0/+2
This patch moves transport dynamic registration and matching to the net module to prevent a bad Kconfig dependency between the net and fs 9p modules. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-10-179p: Make transports dynamicEric Van Hensbergen1-10/+15
This patch abstracts out the interfaces to underlying transports so that new transports can be added as modules. This should also allow kernel configuration of transports without ifdef-hell. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-07-149p: Reorganization of 9p file system codeLatchesar Ionkov1-0/+49
This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p. It moves the transport, packet marshalling and connection layers to net/9p leaving only the VFS related files in fs/9p. This work is being done in preparation for in-kernel 9p servers as well as alternate 9p clients (other than VFS).
