There's race where VFS remount code can race with unlink and result will be unlinked file in orphan list on read-only filesystem. Christian seems to be hitting this race. Miklos Szeredi has patches (http://lkml.indiana.edu/hypermail/linux/kernel/1108.3/00169.html) to mostly close this hole but they're waiting for Al to find time to look at them / merge them AFAIK.While these patches are still pending review, are they "dangerous" to apply? If not, I'd like to volunteer as a tester :-)As far as I saw them, they should be pretty safe. So feel free to test them.
I've applied them to -rc5. It might take a few days untile the message occurs. Or, until "nothing happens", since I have the patches applied :-) Meanwhile I'm trying to reproduce this issue on an x86 machine, but haven't succeeded yet. Thanks, Christian. -- BOFH excuse #133: It's not plugged in.
