Subject: ramdisk rc: start disk drivers synchronously.
X-Git-Tag: v3.1.8~298
X-Git-Url: http://zhaoyanbai.com/repos/dnssec-signzone.html?a=commitdiff_plain;h=71dbe2d023df23d2c4668174e76acacdaf9ac1aa;p=minix.git

ramdisk rc: start disk drivers synchronously.

This eliminates a race condition between the disk driver calling
sys_statectl(SYS_STATE_CLEAR_IPC_REFS) as part of driver_announce(),
and the root MFS calling sendrec(DEV_OPEN) on the disk driver.
