Subject: [PATCH] btrfs - replace div_long_long_rem()

Hi Chris,

While compiling btrfs against 2.6.25-rc8-mm1, ran into this.
div_long_long_rem() is removed in -mm. Replace with div_u64_rem().

Thanks,
Badari

div_long_long_rem() API is being removed (patch in -mm).
Replace div_long_long_rem() with div_u64_rem().
