From bb55b327cb7638d5b5320c766950bfb328636e9f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 22 Sep 2008 19:23:48 -0700 Subject: drivers/net/wan: Use DIV_ROUND_UP The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ #include @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // Signed-off-by: Julia Lawall Signed-off-by: Andrew Morton Signed-off-by: David S.
