nilfs2: do not use unexported cpu_to_le32()/le32_to_cpu() in uapi header
commit c32cc30c0544f13982ee0185d55f4910319b1a79 upstream. cpu_to_le32/le32_to_cpu is defined in include/linux/byteorder/generic.h, which is not exported to user-space. UAPI headers must use the ones prefixed with double-underscore. Detected by compile-testing exported headers: include/linux/nilfs2_ondisk.h: In function `nilfs_checkpoint_set_snapshot': include/linux/nilfs2_ondisk.h:536:17: error: implicit declaration of function `cpu_to_le32' [-Werror=implicit-function-declaration] cp->cp_flags = cpu_to_le32(le32_to_cpu(cp->cp_flags) | \ ^ include/linux/nilfs2_ondisk.h:552:1: note: in expansion of macro `NILFS_CHECKPOINT_FNS' NILFS_CHECKPOINT_FNS(SNAPSHOT, snapshot) ^~~~~~~~~~~~~~~~~~~~ include/linux/nilfs2_ondisk.h:536:29: error: implicit declaration of function `le32_to_cpu' [-Werror=implicit-function-declaration] cp->cp_flags = cpu_to_le32(le32_to_cpu(cp->cp_flags) | \ ^ include/linux/nilfs2_ondisk.h:552:1: note: in expansion of macro `NILFS_CHECKPOINT_FNS' NILFS_CHECKPOINT_FNS(SNAPSHOT, snapshot) ^~~~~~~~~~~~~~~~~~~~ include/linux/nilfs2_ondisk.h: In function `nilfs_segment_usage_set_clean': include/linux/nilfs2_ondisk.h:622:19: error: implicit declaration of function `cpu_to_le64' [-Werror=implicit-function-declaration] su->su_lastmod = cpu_to_le64(0); ^~~~~~~~~~~ Link: http://lkml.kernel.org/r/20190605053006.14332-1-yamada.masahiro@socionext.com Fixes: e63e88bc53ba ("nilfs2: move ioctl interface and disk layout to uapi separately") Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Ryusuke Konishi <konishi.ryusuke@gmail.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Greg KH <gregkh@linuxfoundation.org> Cc: Joe Perches <joe@perches.com> Cc: <stable@vger.kernel.org> [4.9+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
