Move unplugging for direct I/O from around ->direct_IO() down to do_blockdev_direct_IO(). This implicitly adds plugging for direct writes. CC: Li Shaohua <shli@fusionio.com> Acked-by:

Buffered write(2) is not directly tied to IO, so it's not suitable to handle plug in generic_file_aio_write(). Note that plugging for O_SYNC writes is also removed. The user may pass arbitrary @size arguments, which may be much larger than the preferable I/O size, or may cross extent/device boundaries. Let the lower layers handle the plugging. The plugging code here actually turns them into no-ops. CC: Li Shaohua <shli@fusionio.com> Signed-off-by:

I met a odd prblem:read /proc/partitions may return zero. I wrote a file test.c: int main() { char buff[4096]; int ret; int fd; printf("pid=%d\n",getpid()); while (1) { fd = open("/proc/partitions", O_RDONLY); if (fd < 0) { printf("open error %s\n", strerror(errno)); return 0; } ret = read(fd, buff, 4096); if (ret <= 0) printf("ret=%d, %s, %ld\n", ret, strerror(errno), lseek(fd,0,SEEK_CUR)); close(fd); } exit(0); } You can reproduce by: 1:while true;do cat /proc/partitions > /dev/null ;done 2:./test I reviewed the code and found: >> static void *show_partition_start(struct seq_file *seqf, loff_t *pos) >> { >> static void *p; >> >> p = disk_seqf_start(seqf, pos); >> if (!IS_ERR_OR_NULL(p) && !*pos) >> seq_puts(seqf, "major minor #blocks name\n\n"); >> return p; >> } test cat /proc/partitions p = disk_seqf_start()(Not NULL) p = disk_seqf_start()(NULL because pos) if (!IS_ERR_OR_NULL(p) && !*pos) Signed-off-by:

Add a helper to map a bio to a scatterlist, modelled after blk_rq_map_sg. This helper is useful for any driver that wants to create a scatterlist from its ->make_request_fn method.

Paolo Bonzini authored
When a disk has large discard_granularity and small max_discard_sectors, discards are not split with optimal alignment. In the limit case of discard_granularity == max_discard_sectors, no request could be aligned correctly, so in fact you might end up with no discarded logical blocks at all. Another example that helps showing the condition in the patch is with discard_granularity == 64, max_discard_sectors == 128. A request that is submitted for 256 sectors 2..257 will be split in two: 2..129, 130..257. However, only 2 aligned blocks out of 3 are included in the request; 128..191 may be left intact and not discarded. With this patch, the first request will be truncated to ensure good alignment of what's left, and the split will be 2..127, 128..255, 256..257. The patch will also take into account the discard_alignment. At most one extra request will be introduced, because the first request will be reduced by at most granularity-1 sectors, and granularity must be less than max_discard_sectors. Subsequent requests will run on round_down(max_discard_sectors, granularity) sectors, as in the current code. Signed-off-by:

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."

The XRX200 based SoC have a different register offset for the interface clock and PCI control registers. This patch detects the SoC and sets the register offset at runtime. This make PCI work on the VR9 SoC. Signed-off-by:

* set_fs(KERNEL_DS) + getname() is probably the weirdest implementation of strdup() I've seen. Especially since they don't to copy it at all... * filp_open() never returns NULL; it's ERR_PTR(-E...) on failure. * file->f_dentry is never going to be NULL, TYVM. * match_strdup() + snprintf() + kfree() is a bloody weird way to spell match_strlcpy(). Pox on cargo-cult programmers... Signed-off-by:
