* [NET] link_watch: Always schedule urgent eventsHerbert Xu2007-05-101-19/+41
| | | | | | | | | | | | | | | | Urgent events may be delayed if we already have a non-urgent event queued for that device. This patch changes this by making sure that an urgent event is always looked at immediately. I've replaced the LW_RUNNING flag by LW_URGENT since whether work is scheduled is already kept track by the work queue system. The only complication is that we have to provide some exclusion for the setting linkwatch_nextevent which is available in the actual work function.

* [NET] link_watch: Eliminate potential delay on wrap-aroundHerbert Xu2007-05-101-1/+3
| | | | | | | | | | | | When the jiffies wrap around or when the system boots up for the first time, down events can be delayed indefinitely since we no longer update linkwatch_nextevent when only urgent events are processed. This patch fixes this by setting linkwatch_nextevent when a wrap-around occurs. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NET]: Remove link_watch delay for up even when we're downHerbert Xu2007-05-101-23/+67
| | | | | | | | | | | | | Currently all link carrier events are delayed by up to a second before they're processed to prevent link storms. This causes unnecessary packet loss during that interval. In fact, we can achieve the same effect in preventing storms by only delaying down events and unnecssary up events. The latter is defined as up events when we're already up.

* [NET] link_watch: Move link watch list into net_deviceHerbert Xu2007-05-102-35/+17
| | | | | | | | | | | | | | | | | | | | | These days the link watch mechanism is an integral part of the network subsystem as it manages the carrier status. So it now makes sense to allocate some memory for it in net_device rather than allocating it on demand. In fact, this is necessary because we can't tolerate a memory allocation failure since that means we'd have to potentially throw a link up event away. It also simplifies the code greatly. In doing so I discovered a subtle race condition in the use of singleevent. This race condition still exists (and is somewhat magnified) without singleevent but it's now plugged thanks to an smp_mb__before_clear_bit.

* locks: fix F_GETLK regression (failure to find conflicts)J. Bruce Fields2007-05-101-2/+3
| | | | | | | | | | | | | | | | | | | | | | In 9d6a8c5c213e34c475e72b245a8eb709258e968c we changed posix_test_lock to modify its single file_lock argument instead of taking separate input and output arguments. This makes it no longer safe to set the output lock's fl_type to F_UNLCK before looking for a conflict, since that means searching for a conflict against a lock with type F_UNLCK. This fixes a regression which causes F_GETLK to incorrectly report no conflict on most filesystems (including any filesystem that doesn't do its own locking). Also fix posix_lock_to_flock() to copy the lock type. This isn't strictly necessary, since the caller already does this; but it seems less likely to cause confusion in the future.

A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().
