      block: Don't use static to define "void *p" in show_partition_start() · 06768067
      Jianpeng Ma authored
      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)

      Linus Torvalds authored
      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."

      locks: remove unused lm_release_private · 068535f1
      J. Bruce Fields authored
      In commit 3b6e2723 ("locks: prevent side-effects of
      locks_release_private before file_lock is initialized") we removed the
      last user of lm_release_private without removing the field itself.

      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.

      * 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...
