From 565af1cda2d35fa481a732b7405959263f47cc9f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sun, 15 Jan 2017 11:14:07 +0300 Subject: [PATCH] staging: lustre: ptlrpc: silence a shift wrapping warning "svcpt->scp_hist_seq" is a u64 so static checkers complain that 1U should be 1ULL. I looked at REQS_SEQ_SHIFT() a little and it seems to be capped by the number of CPUs online and the amount of memory, but I think it could go above 32 possibly.
