From 9f6c532f59b20580acf8ede9409c9b8dce6e74e1 Mon Sep 17 00:00:00 2001 From: "peterz@infradead.org" Date: Thu, 21 Sep 2023 12:45:10 +0200 Subject: futex: Add sys_futex_wake() To complement sys_futex_waitv() add sys_futex_wake(). This syscall implements what was previously known as FUTEX_WAKE_BITSET except it uses 'unsigned long' for the bitmask and takes FUTEX2 flags. The 'unsigned long' allows FUTEX2_SIZE_U64 on 64bit platforms.
