Jens and Al:
Simple testing seems to show that when a program closes a file descriptor for a block device file, the release method in the device driver's block_device_operations structure doesn't get called (and the close(2) system call doesn't return) until all the dirty pages for that device have been written out.
Can anyone confirm that this always happens? Where in the kernel source is this handled?
Thanks,
Alan Stern
