Subject2.6.0-test7: XFS fills files with 0-bytes after crash
I recently encountered a problem with XFS: while hacking on some network 
stuff
I crashed my box multiple times. Every time I saved a file directly
before the crash
XFS filled the file with 0-bytes (I assume at recovery). The file size
was unchanged.
Syncing and waiting a couple of seconds before crashing the box helped.
To confirm
my network hacking didn't accidentally damage XFS data structures I
created a
module which does nothing more than dereferencing a NULL pointer in softirq
context, the problem persisted.
