Slowly those # have been fixed when the oopses have been tracked down. # # This set of changes fixes the remaining abusers of force_sig and # carefully rips out the task parameter from force_sig and friends # making this kind of error almost impossible in the future" # # * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (27 commits) # signal/x86: Move tsk inside of CONFIG_MEMORY_FAILURE in do_sigbus # signal: Remove the signal number and task parameters from force_sig_info # signal: Factor force_sig_info_to_task out of force_sig_info # signal: Generate the siginfo in force_sig # signal: Move the computation of force into send_signal and correct it. # signal: Properly set TRACE_SIGNAL_LOSE_INFO in __send_signal # signal: Remove the task parameter from force_sig_fault # signal: Use force_sig_fault_to_task for the two calls that don't deliver to current #
