This patch makes these two functions actually use the inferior parameter added by the previous patch, instead of reading inferior_ptid. I chose these two, because they are the one actually used when I detach on my GNU/Linux system, so they were easy to test. I took the opportunity to pass the inferior being detached to inf_ptrace_detach_success, so it could use it too. From there, it made sense to add an overload of detach_inferior that takes the inferior directly rather than the pid, to avoid having to pass inf->pid only for the callee to look up the inferior structure by pid. gdb/ChangeLog: * inf-ptrace.c (inf_ptrace_detach): Adjust call to inf_ptrace_detach_success. (inf_ptrace_detach_success): Add inferior parameter, use it instead of inferior_ptid, pass it to detach_inferior. * inf-ptrace.h (inf_ptrace_detach_success): Add inferior parameter. * inferior.c (detach_inferior): Add overload that takes an inferior object. * inferior.h (detach_inferior): Likewise. * linux-nat.c (linux_nat_detach): Use the inf parameter, don't use inferior_ptid, adjust call to inf_ptrace_detach_success. * linux-thread-db.c (thread_db_detach): Use inf parameter.
