[PATCH 0/4]nbd: fixes for nbd

[Pranay Kr. Srivastava]

This patch series fixes the following

1) fix might_sleep warning on socket shutdown:
   Fix sock_shutdown to avoid calling kernel_sock_shutdown
   while holding spin_lock.

2)fix various coding standard warnings
   Make shutdown get called in a process context instead, using
   system_wq.

3) make nbd device wait for its users.
   When a timeout or error occurs then nbd driver simply kills
   the block device. Many filesystem(s) example ext2/ext3 don't
   expect their buffer heads to disappear like that. Fix this
   by making nbd device wait for its users.

4) use device_attr macros for sysfs attribute
   use DEVICE_ATTR_RO for sysfs pid attribute.
