make blkdev_put() return void

2013-05-07T06:16:31+00:00

same story as with the previous patches - note that return
value of blkdev_close() is lost, since there's nowhere the
caller (__fput()) could return it to.

pnfsblock: cleanup nfs4_blkdev_get

2012-10-08T23:32:40+00:00

It is not needed at all and it is messing with return values...

NFS: Use proper naming conventions for the nfs_client.net field

2012-05-22T20:45:44+00:00

Clean up:  When naming fields and data types, follow established
conventions to facilitate accurate grep/cscope searches.

NFS: replace global bl_wq with per-net one

2012-03-11T14:57:35+00:00

This queue is used for sleeping in kernel and it have to be per-net since we
don't want to wake any other waiters except in out network nemespace.
BTW, move wq to per-net data is easy. But some way to handle upcall timeouts
have to be provided. On message destroy in case of timeout, tasks, waiting for
message to be delivered, should be awakened. Thus, some data required to
located the right wait queue. Chosen solution replaces rpc_pipe_msg object with
new introduced bl_pipe_msg object, containing rpc_pipe_msg and proper wq.

NFS: replace global bl_mount_reply with per-net one

2012-03-11T14:57:34+00:00

This global variable is used for blocklayout downcall and thus can be corrupted
if case of existence of multiple networks namespaces.

NFS: start printks w/ NFS: even if func shown

This patch addresses printks that have some context to show that they are
from fs/nfs/, but for the sake of consistency now start with NFS:

NFS: blocklayout pipe creation per network namespace context introduced

2012-01-31T23:20:27+00:00

This patch implements blocklayout pipe creation and registration per each
existent network namespace.
This was achived by registering NFS per-net operations, responsible for
blocklayout pipe allocation/register and unregister/destruction instead of
initialization and destruction of static "bl_device_pipe" pipe (this one was
removed).
Note, than pointer to network blocklayout pipe is stored in per-net "nfs_net"
structure, because allocating of one more per-net structure for blocklayout
module looks redundant.
This patch also changes dev_remove() function prototype (and all it's callers,
where it' requied) by adding network namespace pointer parameter, which is used
to discover proper blocklayout pipe for rpc_queue_upcall() call.

SUNRPC: split SUNPRC PipeFS dentry and private pipe data creation

2012-01-31T23:20:25+00:00

This patch is a final step towards to removing PipeFS inode references from
kernel code other than PipeFS itself. It makes all kernel SUNRPC PipeFS users
depends on pipe private data, which state depend on their specific operations,
etc.
This patch completes SUNRPC PipeFS preparations and allows to create pipe
private data and PipeFS dentries independently.
Next step will be making SUNPRC PipeFS dentries allocated by SUNRPC PipeFS
network namespace aware routines.
