From 4ba6ce250e406b20bcd6f0f3aed6b3d80965e6c2 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 27 Jun 2010 18:49:59 +0200 Subject: percpu: make @dyn_size always mean min dyn_size in first chunk init functions In pcpu_build_alloc_info() and pcpu_embed_first_chunk(), @dyn_size was ssize_t, -1 meant auto-size, 0 forced 0 and positive meant minimum size. There's no use case for forcing 0 and the upcoming early alloc support always requires non-zero dynamic size. Make @dyn_size always mean minimum dyn_size. While at it, make pcpu_build_alloc_info() static which doesn't have any external caller as suggested by David Rientjes.
