0001-btrfs-tools-include-linux-const.h-to-fix-build-with-.patch
removed since it is included in 5.16

Add 0001-btrfs-progs-kerncompat-add-local-definition-for-alig.patch
to fix "undefined reference to `__ALIGN_KERNEL'".

Changelog:
=========
 - rescue: new subcommand clear-uuid-tree to fix failed mount due to bad uuid
   subvolume keys, caught by tree-checker
 - fi du: skip inaccessible files
 - prop: properly resolve to symlink targets
 - send, receive: fix crash after parent subvolume lookup errors
 - build:
   fix build on 5.12+ kernels due to changes in linux/kernel.h
   fix build on musl with old kernel headers
 - other:
   error handling fixes, cleanups, refactoring
   extent tree v2 preparatory work
   lots of RST documentation updates (last release with asciidoc sources),

+Subject: [PATCH] btrfs-progs: kerncompat: add local definition for alignment
+ macros
+
+There's still problem left with compilation on musl and kernel < 5.11,
+because __ALIGN_KERNEL is not defined anymore:
+
+../bin/ld: kernel-shared/volumes.o: in function `create_chunk':
+volumes.c:(.text+0x17f8): undefined reference to `__ALIGN_KERNEL'
+
+Due to the entangled includes and unconditional definition of
+__ALIGN_KERNEL, we can't use #ifdef in kerncompat.h to define it
+eventually (as kerncompat.h is the first include). Instead add local
+definitions of the macros and rename them to avoid name clashes.
+
+Pull-request: #433
+
+Upstream-Status: Backport [https://github.com/kdave/btrfs-progs/commit/b0cfe12c4d4b8b4ef335cdf4ddefcbdcd1b70d58]

-Subject: [PATCH] btrfs-progs: include linux/const.h to fix build with 5.12+
- headers
-
-btrfs-tools compile fails with mips, musl and 5.12+ headers.
-
-The definition of __ALIGN_KERNEL has moved in 5.12+ kernels, so we
-add an explicit include of const.h to pickup the macro:
-
-  | make: *** [Makefile:595: mkfs.btrfs] Error 1
-  | make: *** Waiting for unfinished jobs....
-  | libbtrfs.a(volumes.o): in function `dev_extent_search_start':
-  | /usr/src/debug/btrfs-tools/5.12.1-r0/git/kernel-shared/volumes.c:464: undefined reference to `__ALIGN_KERNEL'
-  | collect2: error: ld returned 1 exit status
-
-This is safe for older kernel's as well, since the header still
-exists, and is valid to include.
-
-Upstream-Status: Inappropriate [mips64 + musl + libc-headers]
