Re: [Xen-devel] [PATCH v8 02/10] scripts: add coccinelle script to use auto propagated errp

Script adds ERRP_AUTO_PROPAGATE macro invocation where appropriate and
does corresponding changes in code (look for details in
include/qapi/error.h)

Usage example:
spatch --sp-file scripts/coccinelle/auto-propagated-errp.cocci \
  --macro-file scripts/cocci-macro-file.h --in-place --no-show-diff \
  blockdev-nbd.c qemu-nbd.c {block/nbd*,nbd/*,include/block/nbd*}.[hc]

I'll let Markus do the final review of this, but my personal take is that if the subsequent patches created by using this script are reasonable, then this script was good enough.

+// Always use the same patter for checking error

pattern

+@@
+identifier rule1.fn;
+symbol errp;
+@@
+
+ fn(...)
+ {
+     <...
+-    *errp != NULL
++    *errp
+     ...>
+ }
