      Tejun Heo authored
      Dennis rewrote a significant portion of the percpu allocator and has
      shown that he can respond in a timely and helpful manner when issues
      are reported against percpu allocator.
      
      Let's make Dennis the percpu tree maintainer.

      pstore: Fix incorrect persistent ram buffer mapping · 831b624d
      Bin Yang authored
      persistent_ram_vmap() returns the page start vaddr.
      persistent_ram_iomap() supports non-page-aligned mapping.
      
      persistent_ram_buffer_map() always adds offset-in-page to the vaddr
      returned from these two functions, which causes incorrect mapping of
      non-page-aligned persistent ram buffer.
      
      By default ftrace_size is 4096 and max_ftrace_cnt is nr_cpu_ids. Without
      this patch, the zone_sz in ramoops_init_przs() is 4096/nr_cpu_ids which
      might not be page aligned. If the offset-in-page > 2048, the vaddr will be
      in next page. If the next page is not mapped, it will cause kernel panic:

      null_blk: fix zoned support for non-rq based operation · b228ba1c
      Jens Axboe authored
      The supported added for zones in null_blk seem to assume that only rq
      based operation is possible. But this depends on the queue_mode setting,
      if this is set to 0, then cmd->bio is what we need to be operating on.
      Right now any attempt to load null_blk with queue_mode=0 will
      insta-crash, since cmd->rq is NULL and null_handle_cmd() assumes it to
      always be set.
      
      Make the zoned code deal with bio's instead, or pass in the
      appropriate sector/nr_sectors instead.
