[PATCH] Fix multiple conversion bugs in msecs_to_jiffies

2007-02-16T16:13:56+00:00

Fix multiple conversion bugs in msecs_to_jiffies().

The main problem is that this condition:

	if (m > jiffies_to_msecs(MAX_JIFFY_OFFSET))

overflows if HZ is smaller than 1000!

This change is user-visible: for HZ=250 SUS-compliant poll()-timeout
value of -20 is mistakenly converted to 'immediate timeout'.

(The new dyntick code also triggered this, that's how we noticed.)

There are loads of fat functions hidden in jiffies.h.  Uninline them.  No code
changes.

Fix comments: s/granuality/granularity/

2006-03-31T23:41:22+00:00

I was grepping through the code and some `grep ganularity -R .` didn't
catch what I thought. Then looking closer I saw the term "granuality"
used in only four places (in comments) and granularity in many more
places describing the same idea. Some other facts:

dictionary.com does not know such a word
define:granuality on google is not found (and pages for granuality are
mostly related to patches to the kernel)
it has not been discussed as a term on LKML, AFAICS (=Can Search)

To be consistent, I think granularity should be used everywhere.

[PATCH] hrtimers: remove nsec_t typedef

2006-03-26T16:57:03+00:00

nsec_t predates ktime_t and has mostly been superseded by it.  In the few
places that are left it's better to make it explicit that we're dealing with
64 bit values here.

[PATCH] remove pps support

2006-03-25T16:23:02+00:00

This removes the support for pps.  It's completely unused within the kernel
and is basically in the way for further cleanups.  It should be easier to
readd proper support for it after the rest has been converted to NTP4
(where the pps mechanisms are quite different from NTP3 anyway).

[PATCH] Normalize timespec for negative values in ns_to_timespec

2006-02-03T16:32:06+00:00

- In case of a negative nsec value the result of the division must be
  normalized.

- Remove inline from an exported function.

Don't try to "validate" a non-existing timeval.

2006-01-31T18:16:55+00:00

settime() with a NULL timeval is silly but legal.

[PATCH] move capable() to capability.h

2006-01-12T02:42:13+00:00

- Move capable() from sched.h to capability.h;

- Use  where capable() is used
	(in include/, block/, ipc/, kernel/, a few drivers/,
	mm/, security/, & sound/;
	many more drivers/ to go)
