commit 77e736186d8f13246f886164c3e934a34f00af87 Author: John Baldwin <[email protected]> AuthorDate: 2021-04-12 18:43:34 +0000 Commit: John Baldwin <[email protected]> CommitDate: 2021-08-11 22:12:47 +0000 bhyve: Move the gdb_active check to gdb_cpu_suspend(). The check needs to be in the public routine (gdb_cpu_suspend()), not in the internal routine called from various places (_gdb_cpu_suspend()). All the other callers of _gdb_cpu_suspend() already check gdb_active, and this breaks the use of snapshots when the debug server is not enabled since gdb_cpu_suspend() tries to lock an uninitialized mutex.
