[RFC] - Mapping ACPI tables as CACHED
I'd like feedback on the following performance problem & suggestions for a proper solution. Large SGI UV systems (3072p, 5TB) take a long time to boot. A significant part of the boot time is scanning ACPI tables. ACPI tables on UV systems are located in RAM memory that is physically attached to node 0. User ... 22 Jul 2010 12:30

Bluetooth: hidp: Add support for hidraw HIDIOCGFEATURE and HIDIOCSFEATURE
Hi Jiri, what is usb-hid.ko doing here? I would expect a bunch of code duplication with minor difference between USB and Bluetooth. usbhid doesn't have a lot of code for hidraw. Two functions are involved: usbhid_output_raw_report() ... 22 Jul 2010 12:30

[PATCH] setlocalversion: fix version for untaged nontip mercurial revs
The manpage for cut says it will return all lines without the delimiter unless -s is specified. When I backed up my mecurial tree to generate modules, I found that the scm part of localversion was turning up blank.

[PATCHv5] usb: gadget: storage: optional SCSI WRITE FUA bit
MS Windows mounts removable storage in "Removal optimized mode" by default. All the writes to the media are synchronous which is achieved by setting FUA (Force Unit Access) bit in SCSI WRITE(10,12) commands. This prevents I/O requests aggregation in block layer dramatically decreasing performance. This patch bri... 22 Jul 2010 11:24
