H A D | dasd_eckd.c | 336c340b Mon Feb 05 14:17:24 CST 2007 Horst Hummel <horst.hummel@de.ibm.com> [S390] dasd: fix unconditional reserve handling.
The reserve/release IOCTLs sometimes do not work. If second system does a 'steal lock' the pending unit check (Format 3 Msg F) is delivered. Since ERP is disabled for reserve/release, the IOCTL call fails. We have to allow basic ERP (retries) for reserve/release IOCTLs.
