Author: avg Date: Sat Mar 3 15:10:37 2018 New Revision: 330338 URL: https://svnweb.freebsd.org/changeset/base/330338 Log: db_nextframe/amd64: catch up with r328083 to recognize fast_syscall_common Since that change the system call stack traces look like this: ... sys___sysctl() at sys___sysctl+0x5f/frame 0xfffffe0028e13ac0 amd64_syscall() at amd64_syscall+0x79b/frame 0xfffffe0028e13bf0 fast_syscall_common() at fast_syscall_common+0x101/frame 0xfffffe0028e13bf0 So, db_nextframe() stopped recognizing the system call frame. This commit should fix that.
