NFSv4.1 add nfs_inode book keeping for mdsthreshold

2012-05-24T20:15:48Z

Keep track of the number of bytes read or written via buffered, direct, and mem-mapped i/o for use by mdsthreshold size_io hints. Signed-off-by: Andy Adamson Signed-off-by: Trond Myklebust

NFSv4.1 set RPC_TASK_SOFTCONN for filelayout DS RPC calls

2012-05-19T21:54:19Z

RPC_TASK_SOFTCONN returns connection errors to the caller which allows the pNFS file layout to quickly try the MDS or perhaps another DS. Signed-off-by: Andy Adamson Signed-off-by: Trond Myklebust

NFS: Fix sparse warnings

2012-05-04T18:59:51Z

Fix the following sparse warnings: fs/nfs/direct.c:221:6: warning: symbol 'nfs_direct_readpage_release' was not declared. Should it be static? fs/nfs/read.c:38:43: warning: non-ANSI function declaration of function 'nfs_readhdr_alloc' fs/nfs/objlayout/objio_osd.c:214:5: warning: symbol '__alloc_objio_seg' was not declared. Should it be static? Reported-by: Dan Carpenter Signed-off-by: Trond Myklebust Cc: Fred Isaman Cc: Boaz Harrosh

NFS: Clean up nfs read and write error paths

2012-05-01T17:48:13Z

Move the error handling for nfs_generic_pagein() into a single function. Ditto for nfs_generic_flush(). Signed-off-by: Trond Myklebust Cc: Fred Isaman

NFS: Read cleanups

2012-05-01T17:48:13Z

Remove unused variables, and reformat some code. Signed-off-by: Trond Myklebust Cc: Fred Isaman

NFS: rewrite directio read to use async coalesce code

2012-04-27T18:10:38Z

This also has the advantage that it allows directio to use pnfs. Signed-off-by: Fred Isaman Signed-off-by: Trond Myklebust

NFS: create completion structure to pass into page_init functions

2012-04-27T18:10:38Z

Factors out the code that will need to change when directio starts using these code paths. This will allow directio to use the generic pagein and flush routines Signed-off-by: Fred Isaman Signed-off-by: Trond Myklebust

NFS: merge _full and _partial read rpc_ops

2012-04-27T18:10:37Z

Decouple nfs_pgio_header and nfs_read_data, and have (possibly multiple) nfs_read_datas each take a refcount on nfs_pgio_header. For the moment keeps nfs_read_header as a way to preallocate a single nfs_read_data with the nfs_pgio_header. The code doesn't need this, and would be prettier without, but given the amount of churn I am already introducing I didn't want to play with tuning new mempools. This also fixes bug in pnfs_ld_handle_read_error. In the case of desc->pg_bsize < PAGE_CACHE_SIZE, the pages list was empty, causing replay attempt to do nothing.

NFS: create struct nfs_page_array

2012-04-27T18:10:37Z

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
