Subject: [PATCH 1/4] fix: mm: introduce vma->vm_flags wrapper functions (v6.3)
See upstream commit :
commit bc292ab00f6c7a661a8a605c714e8a148f629ef6
Author: Suren Baghdasaryan <surenb@google.com>
Date: Thu Jan 26 11:37:47 2023 -0800
mm: introduce vma->vm_flags wrapper functions
vm_flags are among VMA attributes which affect decisions like VMA merging
and splitting. Therefore all vm_flags modifications are performed after
taking exclusive mmap_lock to prevent vm_flags updates racing with such
operations. Introduce modifier functions for vm_flags to be used whenever
flags are updated. This way we can better check and control correct
locking behavior during these updates.

Subject: [PATCH] src/Kbuild: change missing CONFIG_TRACEPOINTS to warning
Taken from a previous patch to the main lttng-modules Makefile, by
Otavio Salvador:
The lttng-modules are being pulled by the tools-profile image feature,
however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.
This change makes the build do not fail when CONFIG_TRACEPOINTS is not
available, allowing it to be kept being pulled by default.

uuid: Decouple guid_t and uuid_le types and respective macros
The guid_t type and respective macros are being used internally only.
The uuid_le has its user outside the kernel. Decouple these types and
macros, and make guid_t completely internal type to the kernel.

btrfs: pass find_free_extent_ctl to allocator tracepoints
The allocator tracepoints currently have a pile of values from ffe_ctl.
In modifying the allocator and adding more tracepoints, I found myself
adding to the already long argument list of the tracepoints. It makes it
a lot simpler to just send in the ffe_ctl itself.
