      [PATCH] scsi: clear garbage after CDBs on SG_IO · 097b8457
      Tejun Heo authored
      
      
      ATAPI devices transfer fixed number of bytes for CDBs (12 or 16).  Some
      ATAPI devices choke when shorter CDB is used and the left bytes contain
      garbage.  Block SG_IO cleared left bytes but SCSI SG_IO didn't.  This patch
      makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.

      [PATCH] eCryptfs: CIFS nlink fixes · ae56fb16
      Michael Halcrow authored
      
      
      When CIFS is the lower filesystem, the old lower dentry needs to be explicitly
      dropped from inside eCryptfs to force a revalidate.  In addition, when CIFS is
      the lower filesystem, the inode attributes need to be copied back up from the
      lower inode to the eCryptfs inode on an eCryptfs revalidate.

      [PATCH] Fix strange size check in __get_vm_area_node() · 31be8309
      OGAWA Hirofumi authored
      
      
      Recently, __get_vm_area_node() was changed like following
      
       	if (unlikely(!area))
       		return NULL;
      
      -	if (unlikely(!size)) {
      -		kfree (area);
      +	if (unlikely(!size))
       		return NULL;
      -	}
      
      It is leaking `area', also original code seems strange already.
      Probably, we wanted to do this patch.

      On rename, for both the old and new lower dentry objects, eCryptfs is
      missing a dput on the lower parent directory dentry.  This patch will
      prevent the BUG() at fs/dcache.c:613 from being hit after renaming a file
      inside eCryptfs and then doing a umount on the lower filesystem.

       <0>Kernel panic - not syncing: Aiee, killing interrupt handler!
      
      The root cause is that some irq_chip variables, especially ia64_msi_chip,
      initiate their memeber end to point to NULL. __do_IRQ doesn't check
      if irq_chip->end is null and just calls it after processing the interrupt.
      
      As irq_chip->end is called at many places, so I fix it by reinitiating
      irq_chip->end to dummy_irq_chip.end, e.g., a noop function.

      The root cause is the device struct is initialized twice.
      
      If the device is allocated dynamically by platform_device_alloc,
      platform_device_alloc will initialize struct device, then,
      platform_device_add should be used to register the device.
      
      The difference between platform_device_register and platform_device_add is
      platform_device_register will initiate the device while platform_device_add
      won't.
