pnfs: let layoutcommit handle a list of lseg

2011-08-05T04:58:37+00:00

commit a9bae5666d0510ad69bdb437371c9a3e6b770705 upstream.

There can be multiple lseg per file, so layoutcommit should be
able to handle it.

We don't support header padding yet so better off ditching it

pnfs: support for non-rpc layout drivers

2011-05-29T17:53:51+00:00

Non-rpc layout driver such as for objects and blocks
implement their own I/O path and error handling logic.
Therefore bypass NFS-based error handling for these layout drivers.

NFSv4.1: Ensure that layoutget uses the correct gfp modes

2011-05-12T02:52:13+00:00

Currently, writebacks may end up recursing back into the filesystem due to
GFP_KERNEL direct reclaims in the pnfs subsystem.

NFSv4: Ensure we request the ordinary fileid when doing readdirplus

2011-04-27T19:57:16+00:00

When readdir() returns a directory entry for the root of a mounted
filesystem, Linux follows the old convention of returning the inode
number of the covered directory (despite newer versions of POSIX declaring
that this is a bug).
To ensure this continues to work, the NFSv4 readdir implementation requests
the 'mounted-on-fileid' from the server.

However, readdirplus also needs to instantiate an inode for this entry, and
for that, we also need to request the real fileid as per this patch.

NFS: use secinfo when crossing mountpoints

2011-03-24T17:52:42+00:00

A submount may use different security than the parent
mount does.  We should figure out what sec flavor the
submount uses at mount time.
