It seems that some files were removed from USB documentation. Update the links accordingly.

2020-01-28selftests/ftrace: fix glob selftestSven Schnelle1-1/+1
test.d/ftrace/func-filter-glob.tc is failing on s390 because it has ARCH_INLINE_SPIN_LOCK and friends set to 'y'. So the usual __raw_spin_lock symbol isn't in the ftrace function list. Change '*aw*lock' to '*spin*lock' which would hopefully match some of the locking functions on all platforms.

2020-01-28udp: segment looped gso packets correctlyWillem de Bruijn1-0/+3
Multicast and broadcast packets can be looped from egress to ingress pre segmentation with dev_loopback_xmit. That function unconditionally sets ip_summed to CHECKSUM_UNNECESSARY. udp_rcv_segment segments gso packets in the udp rx path. Segmentation usually executes on egress, and does not expect packets of this type. __udp_gso_segment interprets !CHECKSUM_PARTIAL as CHECKSUM_NONE. But the offsets are not correct for gso_make_checksum. UDP GSO packets are of type CHECKSUM_PARTIAL, with their uh->check set to the correct pseudo header checksum. Reset ip_summed to this type. (CHECKSUM_PARTIAL is allowed on ingress, see comments in skbuff.h) Reported-by: syzbot <syzkaller@googlegroups.com> Fixes: cf329aa42b66 ("udp: cope with UDP GRO packet misdirection") Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2020-01-27scripts/find-unused-docs: Fix massive false positivesGeert Uytterhoeven1-1/+1
scripts/find-unused-docs.sh invokes scripts/kernel-doc to find out if a source file contains kerneldoc or not. However, as it passes the no longer supported "-text" option to scripts/kernel-doc, the latter prints out its help text, causing all files to be considered containing kerneldoc. Get rid of these false positives by removing the no longer supported "-text" option from the scripts/kernel-doc invocation.

2020-01-27dm: fix potential for q->make_request_fn NULL pointerMike Snitzer1-2/+7
Move blk_queue_make_request() to dm.c:alloc_dev() so that q->make_request_fn is never NULL during the lifetime of a DM device (even one that is created without a DM table). Otherwise generic_make_request() will crash simply by doing: dmsetup create -n test mount /dev/dm-N /mnt While at it, move ->congested_data initialization out of dm.c:alloc_dev() and into the bio-based specific init method.

2020-01-27selftests: settings: tests can be in subsubdirsMatthieu Baerts1-1/+1
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") adds support for a new per-test-directory "settings" file. But this only works for tests not in a sub-subdirectories, e.g. - tools/testing/selftests/rtc (rtc) is OK, - tools/testing/selftests/net/mptcp (net/mptcp) is not. We have to increase the timeout for net/mptcp tests which are not upstreamed yet but this fix is valid for other tests if they need to add a "settings" file, see the full list with: tools/testing/selftests/*/*/**/Makefile Note that this patch changes the text header message printed at the end of the execution but this text is modified only for the tests that are in sub-subdirectories, e.g. ok 1 selftests: net/mptcp: mptcp_connect.sh Before we had: ok 1 selftests: mptcp: mptcp_connect.sh But showing the full target name is probably better, just in case a subsubdir has the same name as another one in another subdirectory.
