| Subject: libceph: use pg_num_mask instead of pgp_num_mask for pg.seed calc |
| |
| From: Sage Weil <sage@inktank.com> |
| |
| 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. |
