* USB: change interface to usb_lock_device_for_reset()Alan Stern2009-01-071-6/+5
| | | | | | | | | | | | | | | | | | | This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe.

| * virtio: block: dynamic maximum segmentsRusty Russell2008-12-301-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhance the driver to handle whatever maximum segment number the host tells us to handle. Do to this, we need to allocate the scatterlist dynamically. We set max_phys_segments and max_hw_segments to the same value (1 if the host doesn't tell us, since that's safest and all known hosts do tell us). Note that kmalloc'ing the structure for large sg_elems might be problematic: the fix for this is sg_table, but that requires more work. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* | loop: Do not call loop_unplug for not configured loop device.Milan Broz2008-12-291-0/+1

Unfortunately loop_set_fd() set the request queue unplug function, but loop_clr_fd() doesn't clear that. Loop device allows open of non-configured loop in some situations. If the unplug on request queue is called, loop module oopses because of missing lo_backing_file.

* | loop: Flush possible running bios when loop device is released.Milan Broz2008-12-291-3/+35

Otherwise it can lead to situation that caller closes the device, but some bios are still running and endio() function call later OOpses when uses unallocated mempool. This happens for example when running dm-crypt over loop, here is typical oops backtrace: Oops: 0000 [#1] PREEMPT SMP EIP is at mempool_free+0x12/0x6b ... crypt_dec_pending+0x50/0x54 [dm_crypt] crypt_endio+0x9f/0xa7 [dm_crypt] crypt_endio+0x0/0xa7 [dm_crypt] bio_endio+0x2b/0x2e loop_thread+0x37a/0x3b1 do_lo_send_aops+0x0/0x165 autoremove_wake_function+0x0/0x33 loop_thread+0x0/0x3b1 kthread+0x3b/0x61 kthread+0x0/0x61 kernel_thread_helper+0x7/0x10 (But crash is reproducible with different dm targets running over loop device too.)

In many cases the class devices dev_t just points to a random USB device. This fixes the sysfs "duplicate entry" errors.

Worse, this deadlocks keventd and this takes whole box down. I'm going to fix this properly later, but let's unbreak the driver quickly for non-composite devices at least.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This regression was introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code"). This patch fixes a regression where the controller firmware version is not displayed in procfs. The previous patch would be called anytime something changed. This will get called only once for each controller.

* | cciss: fix sysfs broken symlink regressionMike Miller2008-11-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code"). This patch fixes a broken symlink in sysfs that was introduced by the above commit. We broke it in 2.6.27-rc on or about 20080804. Some installers are broken if this symlink does not exist and they may not detect the logical drives configured on the controller. It does not require being backported into 2.6.26.x or earlier kernels.
