-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]
