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. Introduced by commit e50a7a1a "NFS: make NFS client allocated per network namespace context," Tue Jan 10, 2012. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

NFS: create struct nfs_page_array

2012-04-27T18:10:37+00:00

Both nfs_read_data and nfs_write_data devote several fields which can be combined into a single shared struct. Signed-off-by: Fred Isaman Signed-off-by: Trond Myklebust

NFS: create common nfs_pgio_header for both read and write

2012-04-27T18:10:37+00:00

In order to avoid duplicating all the data in nfs_read_data whenever we split it up into multiple RPC calls (either due to a short read result or due to rsize < PAGE_SIZE), we split out the bits that are the same per RPC call into a separate "header" structure. The goal this patch moves towards is to have a single header refcounted by several rpc_data structures. Thus, want to always refer from rpc_data to the header, and not the other way. This patch comes close to that ideal, but the directio code currently needs some special casing, isolated in the nfs_direct_[read_write]hdr_release() functions. This will be dealt with in a future patch. Signed-off-by: Fred Isaman Signed-off-by: Trond Myklebust

NFS: null dereference in dev_remove()

2012-03-13T19:33:08+00:00

In commit 5ffaf85541 "NFS: replace global bl_wq with per-net one" we made "msg" a pointer instead of a struct stored in stack memory. But we forgot to change the memset() here so we're still clearing stack memory instead clearing the struct like we intended. It will lead to a kernel crash.

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

This global variable is used for blocklayout downcall and thus can be corrupted if case of existence of multiple networks namespaces. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust
