     1.8 +    headers_install: fix __packed in exported kernel headers
     1.9 +    
    1.10 +    checkpatch.pl warns about using __attribute__((packed)) in kernel
    1.11 +    headers: "__packed is preferred over __attribute__((packed))". If one
    1.12 +    follows that advice it could cause problems in the exported header
    1.13 +    files, because the outside world doesn't know about this shortcut.
    1.14 +    
    1.15 +    For example busybox will fail to compile:
    1.16 +     CC      miscutils/ubi_attach_detach.o
    1.17 +     In file included from miscutils/ubi_attach_detach.c:27:0:
    1.18 +     /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
    1.19 +     /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
    1.20 +    ...
    1.21 +    
    1.22 +    Fix the problem by substituting __packed with __attribute__((packed)) in
    1.23 +    the header_install.pl script.
