Revision 69a53bf267fa58b89aa659d121dfe38436562a30 authored by Miklos Szeredi on 17 January 2006, 06:14:41 UTC, committed by Linus Torvalds on 17 January 2006, 07:15:30 UTC
Add ability to abort a filesystem connection. With the introduction of asynchronous reads, the ability to interrupt any request is not enough to dissolve deadlocks, since now waiting for the request completion (page unlocked) is independent of the actual request, so in a deadlock all threads will be uninterruptible. The solution is to make it possible to abort all requests, even those currently undergoing I/O to/from userspace. The natural interface for this is 'mount -f mountpoint', but that only works as long as the filesystem is attached. So also add an 'abort' attribute to the sysfs view of the connection.
