Block device files and the page cache

[Alan Stern]

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
