Bauer. * Added proc_doulongvec_minmax, 09/08/99, Carlos H. Bauer. * Changed linked lists to use list.h instead of lists.h, 02/24/00, Bill * Wendling. * The list_for_each() macro wasn't appropriate for the sysctl loop. * Removed it and replaced it with older style, 03/23/00, Bill Wendling */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "../lib/kstrtox.h" #include #include #ifdef CONFIG_X86 #include #include #include #endif #ifdef CONFIG_SPARC #include #endif #ifdef CONFIG_BSD_PROCESS_ACCT #include #endif #ifdef CONFIG_RT_MUTEXES #include #endif #if defined(CONFIG_PROVE_LOCKING) || defined(CONFIG_LOCK_STAT) #include #endif #ifdef CONFIG_CHR_DEV_SG #include #endif #ifdef CONFIG_STACKLEAK_RUNTIME_DISABLE #include #endif #ifdef CONFIG_LOCKUP_DETECTOR #include #endif #if defined(MY_ABC_HERE) || defined(MY_DEF_HERE) #include #endif /* MY_ABC_HERE || MY_DEF_HERE */ #ifdef MY_ABC_HERE #include #endif /* MY_ABC_HERE */ #ifdef MY_ABC_HERE #include #endif /* MY_ABC_HERE */ #if defined(CONFIG_SYSCTL) #ifdef MY_ABC_HERE char gszSynoTtyS0[50] = {0};
