| |
nilfs2 exports a load of inline functions to userspace that call kernel byteswapping functions that don't exist in UAPI. Fix this by making it #include asm/byteorder.h and use the functions declared there.
A better way is probably to remove these inline functions from the nilfs2 header since they are technically broken.
