Subject: sched_ext: Use bitfields for boolean warning flags
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c7e739746dbde9ae401fd88824f5656c5e2361fc;p=thirdparty%2Fkernel%2Fstable.git

sched_ext: Use bitfields for boolean warning flags

Convert warned_zero_slice and warned_deprecated_rq in scx_sched struct to
single-bit bitfields. While this doesn't reduce struct size immediately,
it prepares for future bitfield additions.

v2: Update patch description.
