Subject: mm/mempolicy.c: use enum value MPOL_REBIND_ONCE in mpol_rebind_policy()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89c522c78a6fbc0e24b71e65b65df8b247d5aebd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mm/mempolicy.c: use enum value MPOL_REBIND_ONCE in mpol_rebind_policy()

We have enum definition in mempolicy.h: MPOL_REBIND_ONCE.  It should
replace the magic number 0 for step comparison in function
mpol_rebind_policy.
