Subject[PATCH v4 0/4] nbd: nbd fixes
Date
This patch series fixes the following

1) cleanup nbd_set_socket
Simple fixes to nbd_set_socket.

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

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.

The same work function is used to trigger the kill_bdev as well
do a sock_shutdown, depending on either a timeout/error occured
or a disconnect was issued.

Also avoid scheduling the work_fn in case a timeout for a request
has already occured.

4) use i_size_write to assign nbd device size
Instead of directly assigning nbd block device
size, use i_size_write for modification.

Pranay Kr. Srivastava (4):
cleanup nbd_set_socket
fix might_sleep warning on socket shutdown
make nbd device wait for its users
use i_size_write to assign nbd device size
