The patch titled copy_signal() cleanup: clean thread_group_cputime_init() has been removed from the -mm tree. Its filename was copy_signal-cleanup-clean-thread_group_cputime_init.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: copy_signal() cleanup: clean thread_group_cputime_init() From: Veaceslav Falico <vfalico@xxxxxxxxxx> Remove unneeded initializations in thread_group_cputime_init() and in posix_cpu_timers_init_group(). They are useless after kmem_cache_zalloc() was used in copy_signal().
