[Xen-devel] [RFC PATCH 0/7] libxl: fork: Selective reaping

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

libvirt reaps its children synchronously and has no central pid
registry and no dispatch mechanism.  libxl does have a pid registry so
can provide a selective reaping facility, but that is not currently exposed.

NB that I have compiled this series but I have NOT EXECUTED IT.
The most plausible test environment is a suitably modified libvirt.

 1/7 libxl: fork: Break out checked_waitpid
 2/7 libxl: fork: Break out childproc_reaped_ours
 3/7 libxl: fork: Clarify docs for libxl_sigchld_owner
 4/7 libxl: fork: assert that chldmode is right
 5/7 libxl: fork: Provide libxl_childproc_sigchld_occurred
 6/7 libxl: fork: Provide ..._always_selective_reap
 7/7 libxl: fork: Provide LIBXL_HAVE_SIGCHLD_SELECTIVE_REAP
