      drm/i915/display: Go softly softly on initial modeset failure · b1f195fc
      Chris Wilson authored 
      Reduce the module/device probe error into a mere debug to hide issues
where the initial modeset is failing (after lies told by hw probe) and
the system hangs with a livelock in cleaning up the failed commit.

 "Here are a handful more bugfixes for 5.10.

  Unfortunately, we found some problems with the new READ_PLUS operation
  that aren't easy to fix. We've decided to disable this codepath
  through a Kconfig option for now, but a series of patches going into
  5.11 will clean up the code and fix the issues at the same time. This
  seemed like the best way to go about it.

  Summary:

   - Fix array overflow when flexfiles mirroring is enabled

   - Fix rpcrdma_inline_fixup() crash with new LISTXATTRS

   - Fix 5 second delay when doing inter-server copy

   - Disable READ_PLUS by default"

      NFS: Disable READ_PLUS by default · 21e31401
      Anna Schumaker authored 
      We've been seeing failures with xfstests generic/091 and generic/263
when using READ_PLUS. I've made some progress on these issues, and the
tests fail later on but still don't pass. Let's disable READ_PLUS by
default until we can work out what is going on.

      NFSv4.2: Fix 5 seconds delay when doing inter server copy · fe8eb820
      Dai Ngo authored 
      Since commit b4868b44 ("NFSv4: Wait for stateid updates after
CLOSE/OPEN_DOWNGRADE"), every inter server copy operation suffers 5
seconds delay regardless of the size of the copy. The delay is from
nfs_set_open_stateid_locked when the check by nfs_stateid_is_sequential
fails because the seqid in both nfs4_state and nfs4_stateid are 0.

Fix __nfs42_ssc_open to delay setting of NFS_OPEN_STATE in nfs4_state,
until after the call to update_open_stateid, to indicate this is the 1st
open. This fix is part of a 2 patches, the other patch is the fix in the
source server to return the stateid for COPY_NOTIFY request with seqid 1
instead of 0.

      NFS: Fix rpcrdma_inline_fixup() crash with new LISTXATTRS operation · 1c87b851
      Chuck Lever authored 
      By switching to an XFS-backed export, I am able to reproduce the
ibcomp worker crash on my client with xfstests generic/013.

For the failing LISTXATTRS operation, xdr_inline_pages() is called
with page_len=12 and buflen=128.

- When ->send_request() is called, rpcrdma_marshal_req() does not
  set up a Reply chunk because buflen is smaller than the inline
  threshold. Thus rpcrdma_convert_iovs() does not get invoked at
  all and the transport's XDRBUF_SPARSE_PAGES logic is not invoked
  on the receive buffer.

- During reply processing, rpcrdma_inline_fixup() tries to copy
  received data into rq_rcv_buf->pages because page_len is positive.
  But there are no receive pages because rpcrdma_marshal_req() never
  allocated them.

The result is that the ibcomp worker faults and dies. Sometimes that
causes a visible crash, and sometimes it results in a transport hang
without other symptoms.

RPC/RDMA's XDRBUF_SPARSE_PAGES support is not entirely correct, and
should eventually be fixed or replaced. However, my preference is
that upper-layer operations should explicitly allocate their receive
buffers (using GFP_KERNEL) when possible, rather than relying on
XDRBUF_SPARSE_PAGES.

      selftests: fix poll error in udpgro.sh · 38bf8cd8
      Paolo Abeni authored 
      The test program udpgso_bench_rx always invokes the poll()
syscall with a timeout of 10ms. If a larger timeout is specified
via the command line, udpgso_bench_rx is supposed to do multiple
poll() calls till the timeout is expired or an event is received.

Currently the poll() loop errors out after the first invocation with
no events, and may causes self-tests failure alike:

failed
 GRO with custom segment size            ./udpgso_bench_rx: poll: 0x0 expected 0x1

This change addresses the issue allowing the poll() loop to consume
all the configured timeout.
