# Merge: 440b65232829 902d67a2d40f
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'sched_ext-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
#     
#     Pull sched_ext support from Tejun Heo:
#      "This implements a new scheduler class called ‘ext_sched_class’, or
#       sched_ext, which allows scheduling policies to be implemented as BPF
#       programs.
#     
#       The goals of this are:
#     
#        - Ease of experimentation and exploration: Enabling rapid iteration
#          of new scheduling policies.
#     
#        - Customization: Building application-specific schedulers which
#          implement policies that are not applicable to general-purpose
#          schedulers.
#     
#        - Rapid scheduler deployments: Non-disruptive swap outs of scheduling
#          policies in production environments"
#
