Subject: more cleanup -- using FIELD_SIZEOF() macro
Date: Sun, 10 Feb 2008 11:39:58 +0000	[thread overview]
Message-ID: <alpine.LFD.1.00.0802100637001.9465@localhost.localdomain> (raw)


  the header file include/linux/kernel.h defines:

  #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))

which is a much more pleasant way of calculating the size of a
structure member.  and there's plenty of places in the tree where that
change can be made, which you can see if you search for the
appropriate pattern:

$ grep -Er "sizeof ?\( ?\( ?\([^\*]*[^ ] ?\*\) ?0 ?\)->[^\)]+\)" *
