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
