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. Pranay Kr. Srivastava (4): fix might_sleep warning on socket shutdown. fix various coding standard warnings make nbd device wait for its users. use device_attr macros for sysfs attribute drivers/block/nbd.c | 150 +++++++++++++++++++++++++++++++++++---------------- 1 file changed, 105 insertions(+), 45 deletions(-) -- 1.7.9.5
