[PATCH] sysctl_{,ms_}jiffies: fix oldlen semantics
currently it's
1) if *oldlenp == 0,
don't writeback anything
2) if *oldlenp >= table->maxlen,
don't writeback more than table->maxlen bytes and rewrite *oldlenp
don't look at underlying type granularity
3) if 0 < *oldlenp < table->maxlen,
*cough*
string sysctls don't writeback more than *oldlenp bytes.
OK, that's because sizeof(char) == 1
int sysctls writeback anything in (0, table->maxlen] range
Though accept integers divisible by sizeof(int) for writing.
sysctl_jiffies and sysctl_ms_jiffies don't writeback anything but
sizeof(int), which violates 1) and 2).
So, make sysctl_jiffies and sysctl_ms_jiffies accept
a) *oldlenp == 0, not doing writeback
b) *oldlenp >= sizeof(int), writing one integer.
-EINVAL still returned for *oldlenp == 1, 2, 3.
