[PATCH 8/8] fanotify: send events to userspace over socket reads
fanotify sends event notification to userspace when userspace reads from the fanotify socket. This patch implements the operations that happen at read time. These include opening the file descriptor to the original object and then filling the userspace buffer. The fd should be pollable to indicate when it has dat... 11 Sep 2009 01:51

[PATCH] net: force bridge module(s) to be GPL

[2.6.31-rc9] hotplug SATA vs lockdep: false positive?
When hot-plugging my SATA DVD drive into my laptop, I see a lockdep warning [1]. On closer inspection, both flush_workqueue() and worker_thread() do tricks with lockdep maps. False positive?

[PATCH v2 RFC] char/tty_io: fix legacy pty name when more than 256 pty devices are requested
With kernel 2.6, the number of minors is not 255 anymore. So, it is possible to have more than 255 pty devices. However, the pty_line_name() only provides device names for the first 256 tty/pty devices. This is a bug, since there's no limits for the maximum number of legacy pty devices at Kconfig or at pty.leg... 8 Sep 2009 15:57
