lttng: add 5.x fixup patches to 2.10.8 release
lttng hasn't released 2.10.9, but the stable/2.10 branch contains changes that we need to build against the 5.0 kernel. We add them here as patches, and we can drop them in the future when lttng is updated.

+Subject: [PATCH 1/9] Fix: signal: Distinguish between kernel_siginfo and
+ siginfo (v4.20)
+
+See upstream commit :
+
+ commit ae7795bc6187a15ec51cf258abae656a625f9980
+ Author: Eric W. Biederman <ebiederm@xmission.com>
+ Date: Tue Sep 25 11:27:20 2018 +0200
+
+ signal: Distinguish between kernel_siginfo and siginfo
+
+ Linus recently observed that if we did not worry about the padding
+ member in struct siginfo it is only about 48 bytes, and 48 bytes is
+ much nicer than 128 bytes for allocating on the stack and copying
+ around in the kernel.
+
+ The obvious thing of only adding the padding when userspace is
+ including siginfo.h won't work as there are sigframe definitions in
+ the kernel that embed struct siginfo.
+
+ So split siginfo in two; kernel_siginfo and siginfo. Keeping the
+ traditional name for the userspace definition. While the version that
+ is used internally to the kernel and ultimately will not be padded to
+ 128 bytes is called kernel_siginfo.
+
+ The definition of struct kernel_siginfo I have put in include/signal_types.h
+
+ A set of buildtime checks has been added to verify the two structures have
+ the same field offsets.
+
+ To make it easy to verify the change kernel_siginfo retains the same
+ size as siginfo. The reduction in size comes in a following change.

+ signal: Remove SEND_SIG_FORCED
+
+ There are no more users of SEND_SIG_FORCED so it may be safely removed.
+
+ Remove the definition of SEND_SIG_FORCED, it's use in is_si_special,
+ it's use in TP_STORE_SIGINFO, and it's use in __send_signal as without
+ any users the uses of SEND_SIG_FORCED are now unncessary.
+
+ This makes the code simpler, easier to understand and use. Users of
+ signal sending functions now no longer need to ask themselves do I
+ need to use SEND_SIG_FORCED.

+
+See upstream commit :
+
+ commit 9fe671496b6c286f9033aedfc1718d67721da0ae

+ Date: Mon Oct 1 14:25:08 2018 -0400
+
+ ext4: adjust reserved cluster count when removing extents
+
+ Modify ext4_ext_remove_space() and the code it calls to correct the
+ reserved cluster count for pending reservations (delayed allocated
+ clusters shared with allocated blocks) when a block range is removed
+ from the extent tree. Pending reservations may be found for the clusters
+ at the ends of written or unwritten extents when a block range is removed.
+ If a physical cluster at the end of an extent is freed, it's necessary
+ to increment the reserved cluster count to maintain correct accounting
+ if the corresponding logical cluster is shared with at least one
+ delayed and unwritten extent as found in the extents status tree.
+
+ Add a new function, ext4_rereserve_cluster(), to reapply a reservation
+ on a delayed allocated cluster sharing blocks with a freed allocated
+ cluster. To avoid ENOSPC on reservation, a flag is applied to
+ ext4_free_blocks() to briefly defer updating the freeclusters counter
+ when an allocated cluster is freed. This prevents another thread
+ from allocating the freed block before the reservation can be reapplied.
+
+ Redefine the partial cluster object as a struct to carry more state
+ information and to clarify the code using it.
+
+ Adjust the conditional code structure in ext4_ext_remove_space to
+ reduce the indentation level in the main body of the code to improve
+ readability.

+ commit 96d4f267e40f9509e8a66e2b39e8b95655617693
+ Author: Linus Torvalds <torvalds@linux-foundation.org>
+ Date: Thu Jan 3 18:57:57 2019 -0800
+
+ Remove 'type' argument from access_ok() function
+
+ Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
+ of the user address range verification function since we got rid of the
+ old racy i386-only code to walk page tables by hand.
+
+ It existed because the original 80386 would not honor the write protect
+ bit when in kernel mode, so you had to do COW by hand before doing any
+ user access. But we haven't supported that in a long time, and these
+ days the 'type' argument is a purely historical artifact.
+
+ A discussion about extending 'user_access_begin()' to do the range
+ checking resulted this patch, because there is no way we're going to
+ move the old VERIFY_xyz interface to that model. And it's best done at
+ the end of the merge window when I've done most of my merges, so let's
+ just get this done once and for all.
+
+ This patch was mostly done with a sed-script, with manual fix-ups for
+ the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
+
+ There were a couple of notable cases:
+
+ - csky still had the old "verify_area()" name as an alias.
+
+ - the iter_iov code had magical hardcoded knowledge of the actual
+ values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
+ really used it)
+
+ - microblaze used the type argument for a debug printout
+
+ but other than those oddities this should be a total no-op patch.
+
+ I tried to fix up all architectures, did fairly extensive grepping for
+ access_ok() uses, and the changes are trivial, but I may have missed
+ something. Any missed conversion should be trivially fixable, though.

+Subject: [PATCH 8/9] Fix: btrfs: Remove fsid/metadata_fsid fields from
+ btrfs_info
+
+Introduced in v5.0.
+
+See upstream commit :
+
+ commit de37aa513105f864d3c21105bf5542d498f21ca2
+ Author: Nikolay Borisov <nborisov@suse.com>
+ Date: Tue Oct 30 16:43:24 2018 +0200
+
+ btrfs: Remove fsid/metadata_fsid fields from btrfs_info
+
+ Currently btrfs_fs_info structure contains a copy of the
+ fsid/metadata_uuid fields. Same values are also contained in the
+ btrfs_fs_devices structure which fs_info has a reference to. Let's
+ reduce duplication by removing the fields from fs_info and always refer
+ to the ones in fs_devices. No functional changes.
