From fd5e2dea537bbf0bfb09f79a8b34c148bb502735 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Wed, 28 Aug 2013 17:17:29 -0700 Subject: [PATCH] libceph: use pg_num_mask instead of pgp_num_mask for pg.seed calc commit 9542cf0bf9b1a3adcc2ef271edbcbdba03abf345 upstream. Fix a typo that used the wrong bitmask for the pg.seed calculation. This is normally unnoticed because in most cases pg_num == pgp_num. It is, however, a bug that is easily corrected.
