Subject: dev_close needs the filp number for asynch I/O, dev_io gets suspend_reopen
X-Git-Tag: v3.1.4~272
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/dnssec-revoke.html?a=commitdiff_plain;h=1d7d5aa629799eee079f5008b926195e156f5f85;p=minix.git

dev_close needs the filp number for asynch I/O, dev_io gets suspend_reopen
flag to suspend a process until the filedescriptor is re-opened. Added
dev_reopen, asyn_io, suspended_ep, reopen_reply, asynsend, diag_repl,
close_filp, close_reply, unpause, select_reply1, select_reply2.
