From a26c074c1cf130df95e9c297ef98fdd98348acf0 Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Mon, 20 Jun 2005 23:54:27 +0200 Subject: [PATCH] [PATCH] net/sb1000: replace nicedelay() with ssleep() Use ssleep() instead of nicedelay() to guarantee the task delays as expected. Remove the prototype and definition of nicedelay(). This is a very weird function, because it is called to sleep in terms of usecs, but always sleeps for 1 second, completely ignoring the parameter. I have gone ahead and followed suit, just sleeping for a second in all cases, but maybe someone with the hardware could tell me if perhaps the paramter *should* matter. Additionally, nicedelay() is called in TASK_INTERRUPTIBLE state, but doesn't deal with signals in case these longer delays do not complete, so I believe ssleep() is more appropriate.
