[Qemu-devel] [RESEND][PATCH] Remove 16-character limit on process title

[John Morrissey]

qemu uses prctl() to set its process title. I bumped up against prctl()'s
16-character limit recently, when adding process title support to
libvirt[1][2].

The attached patch overwrites argv instead. Linux seems to maintain the
length of the original args, even when the new args are shorter and
NULL-terminated, so the trailing whitespace in ps(1) output is probably
unavoidable. I've seen the same result with other daemons that overwrite
argv.
