Subject: [KJ] [PATCH] Add ssleep_interruptible()
Date: Mon, 01 Nov 2004 19:18:30 +0000	[thread overview]
Message-ID: <20041101200749.GF1730@us.ibm.com> (raw)
In-Reply-To: <E1CO1vc-00022t-N2@sputnik>

[-- Attachment #1: Type: text/plain, Size: 886 bytes --]

Description: Adds ssleep_interruptible() to allow longer delays to occur
in TASK_INTERRUPTIBLE, similarly to ssleep(). To be consistent with
msleep_interruptible(), ssleep_interruptible() returns the remaining time
left in the delay in terms of seconds. This required dividing the return
value of msleep_interruptible() by 1000, thus a cast to (unsigned long)
to prevent any floating point issues.
