The reasoning behind the assert in link.c:198 is that once you've obtained a write lock on a vmnt, you can't get an additional read lock on the same vmnt. However, that does not always hold for the assert in path.c:281 where the situation could be that you've obtained a read lock and managed to get another read lock (this is possible). In other words, the assert in path.c:281 is not the right place to check for that situation. --- diff --git a/servers/vfs/path.c b/servers/vfs/path.c index a6945458f..8fb047dc1 100644 --- a/servers/vfs/path.c +++ b/servers/vfs/path.c @@ -271,16 +271,6 @@ struct fproc *rfp; symlink.l_vmnt_lock = VMNT_READ; sym_vp = advance(res_vp, &symlink, rfp); - /* Advance caused us to either switch to a different vmnt or we're - * still at the same vmnt.
