From 5a741a41f675a8cff11cdbb20c819e4853ed1499 Mon Sep 17 00:00:00 2001 From: "Chao Li (Evan)" <lic@highgo.com> Date: Tue, 24 Feb 2026 14:11:24 +0800 Subject: [PATCH v1] Fix bug of clearing of waitStart in ProcWakeup() ProcWakeup() incorrectly resets MyProc->waitStart instead of the waitStart field of the process being awakened. Fix by resetting proc->waitStart, which corresponds to the PGPROC being removed from the wait queue. This looks like oversight of 46d6e5f.
