Fix VPD inquiry page wrapper

2010-10-29T04:51:39Z

commit 16d3ea26f82271fef9b1c4523b5e1ea31fa39eec upstream. Fix two bugs in the VPD page wrapper: - Don't return failure if the user asked for page 0 - The end of buffer check failed to account for the page header size and consequently didn't work Signed-off-by: Martin K.

[SCSI] ibmvscsi: Fix oops when an interrupt is pending during probe

2010-07-27T16:53:23Z

A driver needs to be ready to take an interrupt as soon as it registers an interrupt handler. I noticed the following oops when testing kdump: ipr: IBM Power RAID SCSI Device Driver version: 2.5.0 (February 11, 2010) ibmvscsi 30000002: SRP_VERSION: 16.a ibmvscsi 30000002: SRP_VERSION: 16.a Unable to handle kernel paging request for data at address 0x00000000 ... pc: c000000004085e34: .tasklet_action+0xf4/0x1dc ... c000000004086fe4 .__do_softirq+0x16c/0x2c0 c00000000403138c .call_do_softirq+0x14/0x24 c00000000400ee14 .do_softirq+0xa0/0x104 c00000000408690c .irq_exit+0x70/0xd0 c00000000400f190 .do_IRQ+0x214/0x2a8 c000000004004804 hardware_interrupt_entry+0x1c/0x98 --- Exception: 501 (Hardware Interrupt) at c00000000400c544 .raw_local_irq_restore+0x48/0x54 c00000000465d2a8 ._raw_spin_unlock_irqrestore+0x74/0xa0 c0000000040e7f00 .__setup_irq+0x2ec/0x3f0 c0000000040e8198 .request_threaded_irq+0x194/0x22c c00000000446d854 .rpavscsi_init_crq_queue+0x284/0x3f0 c00000000446c764 .ibmvscsi_probe+0x688/0x710 c00000000402903c .vio_bus_probe+0x37c/0x3e4 c000000004403f10 .driver_probe_device+0xec/0x1b8 c000000004404088 .__driver_attach+0xac/0xf4 c000000004403184 .bus_for_each_dev+0x98/0x104 c000000004403c98 .driver_attach+0x40/0x60 c0000000044026f0 .bus_add_driver+0x154/0x324 c0000000044045d0 .driver_register+0xe8/0x1ac c00000000402b2a8 .vio_register_driver+0x54/0x74 c000000004933ea4 .ibmvscsi_module_init+0x80/0xc0 c000000004009834 .do_one_initcall+0x98/0x1d8 c0000000049005b4 .kernel_init+0x27c/0x33c c000000004031550 .kernel_thread+0x54/0x70 srp_task needs to be setup before request_irq.

[SCSI] ipr: fix resource path display and formatting

2010-07-21T20:52:13Z

It was possible to overflow the buffer used to print out the formatted version of the resource path. The fix is to limit the number of bytes that get formatted. This patch also updates the ipr_show_resource_path function to display the resource address for devices that are attached to adapters that don't support resource paths.

SCSI: implement sd_unlock_native_capacity()

2010-06-02T17:50:04Z

Implement sd_unlock_native_capacity() method which calls into hostt->unlock_native_capacity() if implemented. This will be invoked by block layer if partitions extend beyond the end of the device and can be used to implement, for example, on-demand ATA host protected area unlocking.

powerpc/macio: Fix probing of macio devices by using the right of match table

2010-06-02T07:50:38Z

Grant patches added an of mach table to struct device_driver. However, while he changed the macio device code to use that, he left the match table pointer in struct macio_driver and didn't update drivers to use the "new" one, thus breaking the probing. This completes the change by moving all drivers to setup the "new" one, removing all traces of the old one, and while at it (since it changes the exact same locations), I also remove two other duplicates from struct driver which are the name and owner fields.

st: use noop_llseek() instead of default_llseek()

2010-05-27T16:12:56Z

st_open() suggests that llseek() doesn't work: "We really want to do nonseekable_open(inode, filp); here, but some versions of tar incorrectly call lseek on tapes and bail out if that fails. So we disallow pread() and pwrite(), but permit lseeks." Instead of using the fallback default_llseek() the driver should use noop_llseek() which leaves the file->f_pos untouched but succeeds.
