[PATCH 4/5] hid-input: Use a larger event buffer for MT devices
The MT devices produce a lot of data. Tell the underlying input device approximately how many events will be sent per synchronization, to allow for better buffering. The number is a template based on continuously reporting details for each finger on a single hand. Signed-off-by: Henrik Rydberg <rydberg(a)euromail.s... 23 Jun 2010 08:24

[PATCH 5/5] input: evdev: Never leave the client buffer empty after write
When the client buffer is very small and wraps around a lot, it may well be that a write increases the head such that head == tail. If this happens between the point where a poll is triggered and the actual data is being read, there will be no data to read. This is confusing to applications, which might end up clos... 23 Jun 2010 08:24

[PATCH 0/4] input: evdev: Dynamic buffers (rev5)
Hi Dmitry, Please find enclosed the fifth version of the evdev buffer patches. In this version, the buffer scheme is left intact, leaving a single patch to make the client buffers dynamic. Mostly harmless. The rest of the patches are rebased versions of what has already been sent, and summarizes what seems t... 23 Jun 2010 08:24

HID: Fix PicoLCD to allow it to run fbcon and handle unplug while FB in use
Hi Jiri, Do you think This patch can be applied as-is or should I break it up into 2 or 3 patches (one for the 8bpp NULL-pointer dereference, one for switch between 1bpp and 8bpp and one for the refcounting of framebuffer to get things polite on unplug while framebuffer is still in use? Thanks, Bruno On... 30 Jun 2010 06:29

[PATCH 14/40] compat: convert to use COMPAT_SYSCALL_DEFINE#N()
From: Jason Baron <jbaron(a)redhat.com> convert kernel/compat.c to use the new COMPAT_SYSCALL_DEFINE#N macro. Thus, tying these syscalls into the syscall event layer.

[PATCH 09/40] tracing: move __start_ftrace_events and __stop_ftrace_events to header file
From: Jason Baron <jbaron(a)redhat.com> trace_syscalls.c uses __start_ftrace_events and __stop_ftrace_events in order to prune compat syscall ftrace events that are not referenced by the compat syscall table. So move the 'extern' definitions to a common header file. Signed-off-by: Jason Baron <jbaron(a)redhat.com> ... 23 Jun 2010 07:19

[PATCH 20/40] trace syscalls: Considder compat_syscall_nr when verifying syscall_nr
From: Ian Munsie <imunsie(a)au1.ibm.com> With the new compat syscall tracing, either syscall_nr or compat_syscall_nr may be set, so test both before assuming that the initialisation failed.

[PATCH 03/40] ftrace syscalls: Allow arch specific syscall symbol matching
From: Ian Munsie <imunsie(a)au1.ibm.com> Some architectures have unusual symbol names and the generic code to match the symbol name with the function name for the syscall metadata will fail. For example, symbols on PPC64 start with a period and the generic code will fail to match them. This patch splits out the ... 23 Jun 2010 07:19

x86, compat: convert ia32 layer to use
Any reason we need to differenciate between COMPAT_SYSCALL_DEFINE and ARCH_COMPAT_SYSCALL_DEFINE? We don't need this for native system calls, so I can't see the reason to do it for compat system calls. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordo... 24 Jun 2010 10:43
