Subject: [PATCH] Fix brp-strip-static-archive parallelism
ed184b
ed184b
The change made in fc2c986 can break for large values of %_smp_build_ncpus as
ed184b
this many processes are able to overflow the following pipe.

Thanks to Denys Vlasenko for testing this.

This change solves this problem by running a whole processing pileline for each
ed184b
parallel (file) process. This has also the benefit of running at least some
ed184b
stip commands in parallel.

The -n param fro xargs was increased to 32 to further reduce the over head of
ed184b
spawing the helpers as they are now needed for each run of the file command.
