[PATCH 0/8] introduce sysctl SYSCTL_U8_MAX and SYSCTL_LONG_S32_MAX

[wenyang . linux]

From: Wen Yang <wenyang.linux@xxxxxxxxxxx>

The boundary check of multiple modules uses these static variables (such as
two_five_five, n_65535, ue_int_max, etc), and they are also not changed.
Therefore, add them to the shared sysctl_vals and sysctl_long_vals to avoid
duplication. This also reduce the size a bit 

Wen Yang (8):
  sysctl: introduce sysctl SYSCTL_U8_MAX and SYSCTL_LONG_S32_MAX
  rxrpc: delete these duplicate static variables n_65535 and four
  net: ipv6: delete these duplicate static variables two_five_five and
    minus_one
  svcrdma: delete the duplicate static variables zero
  sysctl: delete these duplicate static variables i_zero and
    i_one_hundred
  epoll: delete these duplicate static variables long_zero and long_max
  fs: inotify: delete these duplicate static variables it_zero and
    it_int_max
  ucounts: delete these duplicate static variables ue_zero and
    ue_int_max
