Don't check h->busy_initializing in cciss_open(). Open won't be called before things are ready, but h->busy_initializing won't be unset until after the initial rebuild_lun_table is finished. But, to read the partitions, cciss_open will be called for each logical drive during rebuild_lun_table. If cciss_open checks h->busy_initializing, then the reading of the partition information during the initial rebuild_lun_table will fail, which is especially bad news if it happens to be your boot device.

When rebuild_lun_table is reached via sysfs, the usage count that is checked prior to messing with c0d0 has different constraints (must be zero) than if rebuild_lun_table is reached via ioctl (must be one.)

For c0dx where x is not 0, we handle deletion and addition simply, but for c0d0, there is the special case that even when there's no disk, the device node exists so that the controller may be accessed. So, for c0d0, we only create the sysfs entries once, when a controller is added, and only remove them once, when a controller is being taken down. Signed-off-by: NStephen M.

The following commit made console open fails while booting: commit b50989dc Author: Alan Cox <alan@linux.intel.com> Date: Sat Sep 19 13:13:22 2009 -0700 tty: make the kref destructor occur asynchronously Due to tty release routines run in a workqueue now, error like the following will be reported while booting: INIT open /dev/console Input/output error It also causes hibernation regression to appear as reported at http://bugzilla.kernel.org/show_bug.cgi?id=14229 The reason is that now there's latency issue with closing, but when we open a "closing not finished" tty, -EIO will be returned. Fix it as per the following Alan's suggestion: Fun but it's actually not a bug and the fix is wrong in itself as the port may be closing but not yet being destructed, in which case it seems to do the wrong thing. Opening a tty that is closing (and could be closing for long periods) is supposed to return -EIO. I suspect a better way to deal with this and keep the old console timing is to split tty->shutdown into two functions. tty->shutdown() - called synchronously just before we dump the tty onto the waitqueue for destruction tty->cleanup() - called when the destructor runs. We would then do the shutdown part which can occur in IRQ context fine, before queueing the rest of the release (from tty->magic = 0 ... the end) to occur asynchronously The USB update in -next would then need a call like if (tty->cleanup) tty->cleanup(tty); at the top of the async function and the USB shutdown to be split between shutdown and cleanup as the USB resource cleanup and final tidy cannot occur synchronously as it needs to sleep. In other words the logic becomes final kref put make object unfindable async clean it up Signed-off-by: NDave Young <hidave.darkstar@gmail.com> [ rjw: Rebased on top of 2.6.31-git, reworked the changelog. ] Signed-off-by: N"Rafael J.

I was recently lucky enough to get a 64-CPU system, so my kernel log ends up with 64 lines like: ACPI: CPU0 (power states: C1[C1] C2[C3]) This is pretty useless clutter because this info is already available after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as well as /proc/acpi/processor/CPU*/power.

The message "ACPI: Device needs an ACPI driver" is misleading. The device _may_ need an ACPI driver, if the BIOS implemented a custom API for the device in question (which, AFAIK, can't be checked.) If not, then either a generic ACPI driver may be used (for example "thermal"), or nothing can be done (other than a white list). I propose to reword the message to: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver which I think is more correct. Comments and suggestions welcome. I also added a message warning about possible problems and system instability when users pass acpi_enforce_resources=lax, as suggested by Len.
