xieliujie 260bfad693 ANDROID: vendor_hook: Add hooks to support reader optimistic spin in rwsem ... Since upstream commit 617f3ef951 ("locking/rwsem: Remove reader optimistic spinning"), vendors have seen increased contention and blocking on rwsems. There are attempts to actively fix this upstream: https://lore.kernel.org/lkml/20240406081126.8030-1-bongkyu7.kim@samsung.com/ But in the meantime, provide vendorhooks so that vendors can implement their own optimistic spin routine. In doing so, vendors see improvements in cold launch times on important apps.
