@ -37,30 +37,31 @@ The network filesystem helper library needs a place to store a bit of state for
its use on each netfs inode it is helping to manage. To this end, a context
structure is defined::
struct netfs_i_context {
struct netfs_inode {
struct inode inode;
const struct netfs_request_ops *ops;
struct fscache_cookie *cache;
struct fscache_cookie *cache;
};
A network filesystem that wants to use netfs lib must place one of these
directly after the VFS ``struct inode`` it allocates, usually as part of its
own struct. This can be done in a way similar to the following::
A network filesystem that wants to use netfs lib must place one of these in its
inode wrapper struct instead of the VFS ``struct inode``. This can be done in
a way similar to the following::
struct my_inode {
struct {
/* These must be contiguous */
struct inode vfs_inode;
struct netfs_i_context netfs_ctx;
};
struct netfs_inode netfs; /* Netfslib context and vfs inode */
...
};
This allows netfslib to find its state by simple offset from the inode pointer,
thereby allowing the netfslib helper functions to be pointed to directly by the
VFS/VM operation tables.
This allows netfslib to find its state by using ``container_of()`` from the
inode pointer, thereby allowing the netfslib helper functions to be pointed to
directly by the VFS/VM operation tables.
The structure contains the following fields:
* ``inode``
The VFS inode structure.
* ``ops``
The set of operations provided by the network filesystem to netfslib.
@ -78,14 +79,12 @@ To help deal with the per-inode context, a number helper functions are
provided. Firstly, a function to perform basic initialisation on a context and
set the operations table pointer::
void netfs_i_context_init(struct inode *inode,
const struct netfs_request_ops *ops);
void netfs_inode_init(struct inode *inode,
const struct netfs_request_ops *ops);
then two functions to cast between the VFS inode structure and the netfs
context::
then a function to cast from the VFS inode structure to the netfs context::
struct netfs_i_context *netfs_i_context(struct inode *inode);
struct inode *netfs_inode(struct netfs_i_context *ctx);
struct netfs_inode *netfs_node(struct inode *inode);
and finally, a function to get the cache cookie pointer from the context
attached to an inode (or NULL if fscache is disabled)::
