   4 Subject: [PATCH] include linux/stddef.h in swab.h uapi header
   5
   6 swab.h uses __always_inline without including the header where it is
   7 defined, this is exposed by musl based distributions where this macro is
   8 not defined by system C library headers unlike glibc where it is defined
   9 in sys/cdefs.h and that header gets pulled in indirectly via
  10
  11 features.h -> sys/cdefs.h
  12
  13 and features.h gets pulled in a lot of headers. Therefore it may work in
  14 cases where features.h is includes but not otherwise.
  15
  16 Adding linux/stddef.h here ensures that __always_inline is always
  17 defined independent of which C library is used in userspace
