We need to call fscache_wait_on_page_write in launder_page
for fscache

9p: Add a Direct IO support for non-cached operations.

2010-10-28T14:08:45+00:00

The presence of v9fs_direct_IO() in the address space ops vector
allowes open() O_DIRECT flags which would have failed otherwise.

In the non-cached mode, we shunt off direct read and write requests before
the VFS gets them, so this method should never be called.

Direct IO is not 'yet' supported in the cached mode. Hence when
this routine is called through generic_file_aio_read(), the read/write fails
with an error.

9p: Add fscache support to 9p

2009-09-23T18:03:46+00:00

This patch adds a persistent, read-only caching facility for
9p clients using the FS-Cache caching backend.

When the fscache facility is enabled, each inode is associated
with a corresponding vcookie which is an index into the FS-Cache
indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
- session object associated with each mount.
- inode/vcookie
- actual data (pages)

A cache tag is chosen randomly for each session. These tags can
be read off /sys/fs/9p/caches and can be passed as a mount-time
parameter to re-attach to the specified caching session.

9p: Fix incorrect parameters to v9fs_file_readn.

2009-07-14T20:54:42+00:00

Fix v9fs_vfs_readpage. The offset and size parameters to v9fs_file_readn
were interchanged and hence passed incorrectly.

9p: move readn meta-function from client to fs layer

2008-10-17T16:04:43+00:00

There are a couple of methods in the client code which aren't actually
wire operations.  To keep things organized cleaner, these operations are
being moved to the fs layer.

This patch moves the readn meta-function (which executes multiple wire
reads until a buffer is full) to the fs layer.

9p: Documentation updates

2008-05-15T00:23:25+00:00

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.

9p: Reorganization of 9p file system code

2007-07-14T20:13:40+00:00

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).
