2012-09-04NFS: Fix the initialisation of the readdir 'cookieverf' arrayTrond Myklebust1-5/+0
When the NFS_COOKIEVERF helper macro was converted into a static inline function in commit 99fadcd764 (nfs: convert NFS_*(inode) helpers to static inline), we broke the initialisation of the readdir cookies, since that depended on doing a memset with an argument of 'sizeof(NFS_COOKIEVERF(inode))' which therefore changed from sizeof(be32 cookieverf[2]) to sizeof(be32 *). At this point, NFS_COOKIEVERF seems to be more of an obfuscation than a helper, so the best thing would be to just get rid of it.

2012-07-31nfs: enable swap on NFSMel Gorman1-2/+2
Implement the new swapfile a_ops for NFS and hook up ->direct_IO. This will set the NFS socket to SOCK_MEMALLOC and run socket reconnect under PF_MEMALLOC as well as reset SOCK_MEMALLOC before engaging the protocol ->connect() method. PF_MEMALLOC should allow the allocation of struct socket and related objects and the early (re)setting of SOCK_MEMALLOC should allow us to receive the packets required for the TCP connection buildup.

2012-05-01NFS: Adapt readdirplus to application usage patternsTrond Myklebust1-5/+0
While the use of READDIRPLUS is significantly more efficient than READDIR followed by many LOOKUP calls, it is still less efficient than just READDIR if the attributes are not required. This patch tracks when lookups are attempted on the directory, and uses that information to selectively disable READDIRPLUS on that directory. The first 'readdir' call is always served using READDIRPLUS. Subsequent calls only use READDIRPLUS if there was a successful lookup or revalidation on a child in the mean time. Credit for the original idea should go to Neil Brown. See: http://www.spinics.net/lists/linux-nfs/msg19996.html However, the implementation in this patch differs from Neil's in that it focuses on tracking lookups rather than calls to stat().

2012-04-27NFS: create struct nfs_commit_infoFred Isaman1-4/+1
It is COMMIT that is handled the most differently between the paged and direct paths. Create a structure that encapsulates everything either path needs to know about the commit state. We could use void to hide some of the layout driver stuff, but Trond suggests pulling it out to ensure type checking, given the huge changes being made, and the fact that it doesn't interfere with other drivers.

2012-04-27NFS: create common nfs_pgio_header for both read and writeFred Isaman1-12/+0
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 <[email protected]> Signed-off-by: Trond Myklebust <[email protected]>

2011-11-04nfs: when attempting to open a directory, fall back on normal lookup (try #5)Jeff Layton1-0/+3
commit d953126 changed how nfs_atomic_lookup handles an -EISDIR return from an OPEN call. Prior to that patch, that caused the client to fall back to doing a normal lookup. When that patch went in, the code began returning that error to userspace. The d_revalidate codepath however never had the corresponding change, so it was still possible to end up with a NULL ctx->state pointer after that. That patch caused a regression. When we attempt to open a directory that does not have a cached dentry, that open now errors out with EISDIR. If you attempt the same open with a cached dentry, it will succeed. Fix this by reverting the change in nfs_atomic_lookup and allowing attempts to open directories to fall back to a normal lookup Also, add a NFSv4-specific f_ops->open routine that just returns -ENOTDIR. This should never be called if things are working properly, but if it ever is, then the dprintk may help in debugging. To facilitate this, a new file_operations field is also added to the nfs_rpc_ops struct.

If the directory contents change, then we have to accept that the file->f_pos value may shrink if we do a 'search-by-cookie'. In that case, we should turn off the loop detection and let the NFS client try to recover.

2011-03-23NFSv4.1: add generic layer hooks for pnfs COMMITFred Isaman1-0/+1
We create three major hooks for the pnfs code. pnfs_mark_request_commit() is called during writeback_done from nfs_mark_request_commit, which gives the driver an opportunity to claim it wants control over commiting a particular req. pnfs_choose_commit_list() is called from nfs_scan_list to choose which list a given req should be added to, based on where we intend to send it for COMMIT. It is up to the driver to have preallocated list headers for each destination it may need. pnfs_commit_list() is how the driver actually takes control, it is used instead of nfs_commit_list(). In order to pass information between the above functions, we create a union in nfs_page to hold a lseg (which is possible because the req is not on any list while in transition), and add some flags to indicate if we need to use the pnfs code.
