[PATCH 1/2] kfifo: implement missing __kfifo_skip_r()
kfifo_skip() is currently broken, due to the missing of the internal helper function. Add it.

dmaengine questions
Hi, I am currently looking into implementing the Freescale i.MX SDMA engine into the dmaengine API. The SDMA engine can handle sg transfers from/to devices. During implementation some questions came up. On the i.MX we already have a DMA engine which can do slave dma transfers, the IPU (drivers/dma/ipu/), which... 13 Aug 2010 03:50

[PATCH 2/4] dio: add page locking for direct I/O

[PATCH]: local_irq_save/restore when issuing IPI in early bootup
When sending out an IPI interrupts are masked off. In the cpu wakeup code, this is not the case. Make the code consistent. Alok Kataria noticed the following hang: 1. vcpu1 is doing wakeup_secondary_cpu_via_init() is booting all the other processors. It tries to bring each cpu up by sending an IPI which is ... 12 Aug 2010 10:22
SCSI: fix bio.bi_rw handling
Jiri Slaby <jslaby(a)suse.cz> writes: Return of the bi_rw tests is no longer bool after commit 74450be1. So testing against constants doesn't make sense anymore. Fix this bug in osd_req_read by removing "== 1" in test. This is not a problem now, where REQ_WRITE is 1, but this can change in the future ... 12 Aug 2010 12:34
BLOCK: fix bio.bi_rw handling
Jiri Slaby <jslaby(a)suse.cz> writes: Return of the bi_rw tests is no longer bool after commit 74450be1. But results of such tests are stored in bools. This doesn't fit in there for some compilers (gcc 4.5 here), so either use !! magic to get real bools or use ulong where the result is assigned somewhere. ... 12 Aug 2010 12:34
