That SRCU fix for KLP introduced large (as in minutes) boot-time delays to embedded Linux kernels running on qemu/KVM. These delays were due to the emulation of certain MMIO operations controlling memory layout, which were emulated with one expedited grace period per access. Common configurations required thousands of boot-time MMIO accesses, and thus thousands of boot-time expedited SRCU grace periods. In these configurations, the occasional sleeps that allowed KLP to proceed caused excessive boot delays. These commits preserve enough sleeps to permit KLP to proceed, but few enough that the virtual embedded kernels still boot reasonably quickly. This represents a regression introduced in the v5.19 merge window, and the bug is causing significant inconvenience" * tag 'rcu-urgent.2022.07.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: srcu: Make expedited RCU grace periods block even less frequently srcu: Block less aggressively for expedited grace periods 2022-07-22T11:38:16+00:00 Rob Herring robh@kernel.org 2022-07-19T21:51:08+00:00 urn:sha1:030f21ba2ab14c221ff31cf22a16c78963328f6f The phy-reset-* properties are missing type definitions and are not common properties.
