Building with gcc 8.2 against musl libc, which apparently has more attributes
available in its sched_param. The following warnings were produced:
warning: missing initializer for member 'sched_param::sched_ss_low_priority' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_repl_period' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_init_budget' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_max_repl' [-Wmissing-field-initializers]
Since the current thread may have interesting non-zero values for these fields,
we want to be sure to only change the intended one. Query and modify the
current sched_param rather than starting from a zeroed one.

Concept ACK Nice find! |
|
Concept ACK I assume this turned up during some 🐢 related work? I'm planning on getting setup to test that/musl going forward, so will give a proper ACK here if I get that done before this is merged. |
| Needs rebase |
|
@theuni I'd like to reproduce by building against musl myself - do you remember which build parameters you used? :-) |
|
Rebased in #14839. |
