2009-10-30Driver core: allow certain drivers prohibit bind/unbind via sysfsDmitry Torokhov
Platform drivers registered via platform_driver_probe() can be bound to devices only once, upon registration, because discard their probe() routines to save memory. Unbinding the driver through sysfs 'unbind' leaves the device stranded and confuses users so let's not create bind and unbind attributes for such drivers.

strstrip() can return a modified value of its input argument, when removing elading whitesapce. So it is surely bug for this function's return value to be ignored.

2009-10-29param: fix lots of bugs with writing charp params from sysfs, by leaking mem.Rusty Russell
e180a6b7759a "param: fix charp parameters set via sysfs" fixed the case where charp parameters written via sysfs were freed, leaving drivers accessing random memory. Unfortunately, storing a flag in the kparam struct was a bad idea: it's rodata so setting it causes an oops on some archs. But that's not all: 1) module_param_array() on charp doesn't work reliably, since we use an uninitialized temporary struct kernel_param. 2) there's a fundamental race if a module uses this parameter and then it's changed: they will still access the old, freed, memory. The simplest fix (ie. for 2.6.32) is to never free the memory. This prevents all these problems, at cost of a memory leak. In practice, there are only 18 places where a charp is writable via sysfs, and all are root-only writable.

2009-10-23perf events: Fix swevent hrtimer sampling by keeping track of remaining time ↵Soeren Sandmann
when enabling/disabling swevent hrtimers Make the hrtimer based events work for sysprof. Whenever a swevent is scheduled out, the hrtimer is canceled. When it is scheduled back in, the timer is restarted. This happens every scheduler tick, which means the timer never expired because it was getting repeatedly restarted over and over with the same period. To fix that, save the remaining time when disabling; when reenabling, use that saved time as the period instead of the user-specified sampling period. Also, move the starting and stopping of the hrtimers to helper functions instead of duplicating the code.

2009-10-22virtio: let header files include virtio_ids.hChristian Borntraeger
Rusty, commit 3ca4f5ca73057a617f9444a91022d7127041970a virtio: add virtio IDs file moved all device IDs into a single file. While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.

This patch (as1295) fixes a recently-added bug in the USB serial core. If certain kinds of errors occur during probing, the core may call a serial driver's release method without previously calling the attach method. This causes some drivers (io_ti in particular) to perform an invalid memory access. The patch adds a new flag to keep track of whether or not attach has been called.

2009-10-07tracing: correct module boundaries for ftrace_releasejolsa@redhat.com
When the module is about the unload we release its call records. The ftrace_release function was given wrong values representing the module core boundaries, thus not releasing its call records. Plus making ftrace_release function module specific.

2009-10-06block: Seperate read and write statistics of in_flight requests v2Nikanth Karthikesan
Commit a9327cac440be4d8333bba975cbbf76045096275 added seperate read and write statistics of in_flight requests. And exported the number of read and write requests in progress seperately through sysfs. But Corrado Zoccolo <czoccolo@gmail.com> reported getting strange output from "iostat -kx 2". Global values for service time and utilization were garbage. For interval values, utilization was always 100%, and service time is higher than normal. So this was reverted by commit 0f78ab9899e9d6acb09d5465def618704255963b The problem was in part_round_stats_single(), I missed the following: if (now == part->stamp) return; - if (part->in_flight) { + if (part_in_flight(part)) { __part_stat_add(cpu, part, time_in_queue, part_in_flight(part) * (now - part->stamp)); __part_stat_add(cpu, part, io_ticks, (now - part->stamp)); With this chunk included, the reported regression gets fixed.

2009-10-06perf_event: Provide vmalloc() based mmap() backingPeter Zijlstra
Some architectures such as Sparc, ARM and MIPS (basically everything with flush_dcache_page()) need to deal with dcache aliases by carefully placing pages in both kernel and user maps. These architectures typically have to use vmalloc_user() for this. However, on other architectures, vmalloc() is not needed and has the downsides of being more restricted and slower than regular allocations.

2009-10-05Input: fix rx51 board keymapAmit Kucheria
The original driver was written with the KEY() macro defined as (col, row) instead of (row, col) as defined by the matrix keypad infrastructure. So the keymap was defined accordingly. Since the driver that was merged upstream uses the matrix keypad infrastructure, modify the keymap accordingly. While we are at it, fix the comments in twl4030.h and define PERSISTENT_KEY as (r,c) instead of (c, r) Tested on a RX51 (N900) device.
