* bugfixes: NFSv4: Return delegations synchronously in evict_inode SUNRPC: Fix a regression when reconnecting NFS: remount with security change should return EINVAL nfs: do not export discarded symbols NFSv4.1: don't export static symbol
2015-03-27NFSv4.1/pnfs: Separate out metadata and data consistency for pNFSTrond Myklebust1-0/+10
The LAYOUTCOMMIT operation means different things to different layout types. For blocks and objects, it is both a data and metadata consistency operation. For files and flexfiles, it is only a metadata consistency operation. This patch separates out the 2 cases, allowing the files/flexfiles layout drivers to optimise away the data consistency calls to layoutcommit.

2015-03-12nfs: do not export discarded symbolsArnd Bergmann1-1/+1
The function nfs4_pnfs_v3_ds_connect_unload is exported so it can be used by other modules, but is also marked '__exit' and will be discarded when built into the kernel, as pointed out by this linker error: `nfs4_pnfs_v3_ds_connect_unload' referenced in section `___ksymtab_gpl+nfs4_pnfs_v3_ds_connect_unload' of fs/built-in.o: defined in discarded section `.exit.text' of fs/built-in.o This removes the __exit annotation to make it safe to call this function.

2015-02-18pnfs: Refactor the *_layout_mark_request_commit to use pnfs_layout_mark_request_commitTom Haynes1-0/+30
The File Layout's filelayout_mark_request_commit() is almost the Flex File Layout's ff_layout_mark_request_commit(). And that can be reduced by calling into nfs_request_add_commit_list().

2015-02-03pnfs: pass ds_commit_idx through the commit pathWeston Andros Adamson1-2/+2
Pass ds_commit_idx through the nfs commit path. It's used to select the commit bucket when using pnfs and is ignored when not using pnfs. Several functions had to be changed: nfs_retry_commit, nfs_mark_request_commit, pnfs_mark_request_commit and the pnfs layout driver .mark_request_commit functions.

2015-02-03nfs/filelayout: use pnfs_error_mark_layout_for_returnPeng Tao1-10/+0
Instead of calling layoutreturn directly, call pnfs_error_mark_layout_for_return to mark layouts for return and let generic code return layout when layout segments are freed.
