1. If the intention is to coalesce requests 'prev' and 'req' then we have to ensure at least that we have a layout starting at req_offset(prev). 2. If we're only requesting a minimal layout of length desc->pg_count, we need to test the length actually returned by the server before we allow the coalescing to occur. 3. We need to deal correctly with (pgio->lseg == NULL) 4. Fixup the test guarding the pnfs_update_layout. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Andy's last device_cache patches, already take an extra reference on the newly inserted device_id. So we can remove it from obj-io. Without this patch the device_ids are leaked. Andy's patches are not in Linus tree yet. So I'm not sure if they are scheduled for this Kernel or the next. This patch should be added as part of these.

Commit 7ebb9315 (NFS: use secinfo when crossing mountpoints) introduces a regression when decoding an NFSv4 readdir entry that sets the rdattr_error field. By treating the resulting value as if it is a decoding error, the current code may cause us to skip valid readdir entries.

nfs_update_inode will update isize if there is no queued pages. For pNFS, layoutcommit is supposed to change file size on server, the same effect as queued pages. nfs_update_inode may be called when dirty pages are written back (nfsi->npages==0) but layoutcommit is not sent, and it will change client file size according to server file size. Then client ends up losing what it just writes back in pNFS path. So we should skip updating client file size if file needs layoutcommit.

By default, unless pnfs is used coalesce pages until pg_bsize (rsize or wsize) is reached. pnfs layout drivers define their own pg_test methods that use pnfs_generic_pg_test and need to define their own I/O size limits (e.g. based on the file stripe size).

An io_state pre-allocates an error information structure for each possible osd-device that might error during IO. When IO is done if all was well the io_state is freed. (as today). If the I/O has ended with an error, the io_state is queued on a per-layout err_list. When eventually encode_layoutreturn() is called, each error is properly encoded on the XDR buffer and only then the io_state is removed from err_list and de-allocated. It is up to the io_engine to fill in the segment that fault and the type of osd_error that occurred. By calling objlayout_io_set_result() for each failing device. In objio_osd: * Allocate io-error descriptors space as part of io_state * Use generic objlayout error reporting at end of io.

A pNFS client auto-negotiates a lot of features (minorversion level, pNFS layout type, etc.). This is convenient, but makes certain kinds of failures hard for a user to detect. For example, if the client falls back on 4.0, or falls back to MDS IO because the user didn't connect to the right iscsi disks before mounting, the only symptoms may be reduced performance, which may not be noticed till long after the actual failure, and may be difficult for a user to diagnose. However, such "failures" may also be perfectly normal in some cases, so we don't want to spam the system logs with them. One approach would be to put some more information into /proc/self/mountstats.
