Subject: 2.4.19' drivers/block/ll_rw_blk.c
Date: Mon, 5 Aug 2002 12:23:29 +0200	[thread overview]
Message-ID: <200208051223.29329.mcp@linux-systeme.de> (raw)

Hi there,

could you please consider changing those very slow behaviour in 
"drivers/block/ll_rw_blk.c"? ... Benchmarked against 2.4.18 this is horribly 
slower ... Doing some heavy disk i/o, want to start another thing, system 
freeze for some seconds ... Opening a xterm , Ctrl-D to leave, this takes 
about 5 seconds and somewhat is doing flushing to the disk.

Maybe req_finished_io ?

Adrian, could this be the problem you've experienced?

Afaik this was changed for 2.4.19-pre7 and above.
