Removed remnants of old function definitions which have since been removed in earlier cleanup work. Signed-off-by: Bart Westgeest <bart@elbrys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-08-25staging: Add module.h to drivers/staging usersPaul Gortmaker
Lots of people expect module.h to just "be there" without any #include effort. But we are crushing that. So fix those files in staging relying on implicit module.h presence. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-03-02staging/usbip: convert to kthreadArnd Bergmann
usbip has its own infrastructure for managing kernel threads, similar to kthread. By changing it to use the standard functions, we can simplify the code and get rid of one of the last BKL users at the same time. Includes changes suggested by Max Vozeler.

2011-01-20staging: usbip: stub: update refcounts for devices and interfacesMax Vozeler
The stub driver expects to access the usb interface and usb device structures even if the device has been disconnected in the meantime. This change gets a reference to them in the stub probe function using usb_get_intf()/usb_get_dev() and drops them in the disconnect function. This fixes an oops observed with a Logic Controls Line display (0fa8:a030) which disconnects itself when it is reset: [ 1348.562274] BUG: unable to handle kernel paging request at 5f7433e5 [ 1348.562327] IP: [<c0393b02>] usb_lock_device_for_reset+0x22/0xd0 [ 1348.562374] *pde = 00000000 [ 1348.562397] Oops: 0000 [#1] [ 1348.562418] last sysfs file: /sys/devices/pci0000:00/0000:00:10.2/usb4/4-1/bConfigurationValue [ 1348.562454] Modules linked in: usbip vhci_hcd usbip_common_mod fbcon tileblit font bitblit softcursor serio_raw uvesafb pcspkr via_rng snd_via82xx gameport snd_ac97_codec ac97_bus snd_pcm_oss snd_mixer_oss snd_pcm snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_oss snd_seq_midi_event snd_seq snd_timer snd_seq_device snd usbhid hid via_rhine soundcore mii igel_flash aufs pata_via [ 1348.562649] [ 1348.562670] Pid: 2855, comm: usbip_eh Not tainted (2.6.32 #23.37-ud-r113) M300C [ 1348.562704] EIP: 0060:[<c0393b02>] EFLAGS: 00010216 CPU: 0 [ 1348.562734] EIP is at usb_lock_device_for_reset+0x22/0xd0 [ 1348.562762] EAX: 5f7433cd EBX: 5f7433cd ECX: de293a5c EDX: dd326a00 [ 1348.562793] ESI: 5f7433cd EDI: 000400f6 EBP: cf43ff48 ESP: cf43ff38 [ 1348.562824] DS: 007b ES: 007b FS: 0000 GS: 00e0 SS: 0068 [ 1348.562854] Process usbip_eh (pid: 2855, ti=cf43e000 task=d2c7f230 task.ti=cf43e000) [ 1348.562884] Stack: [ 1348.562900] d6ec9960 de2939cc 5f7433cd 5f743431 cf43ff70 df8fd32f de2939cc d2c7f230 [ 1348.562940] <0> cf43ff70 00000282 00000282 de2939cc d2c7f230 d2c7f230 cf43ffa8 df84416d [ 1348.562987] <0> cf43ff88 d2c7f230 de293a24 d2c7f230 00000000 d2c7f230 c014e760 cf43ff94 [ 1348.563042] Call Trace: [ 1348.563073] [<df8fd32f>] ? stub_device_reset+0x3f/0x110 [usbip] [ 1348.563114] [<df84416d>] ? event_handler_loop+0xcd/0xe8 [usbip_common_mod] [ 1348.563156] [<c014e760>] ? autoremove_wake_function+0x0/0x50 [ 1348.563193] [<df843d80>] ? usbip_thread+0x0/0x60 [usbip_common_mod] [ 1348.563230] [<df843dd1>] ? usbip_thread+0x51/0x60 [usbip_common_mod] [ 1348.563265] [<c014e374>] ? kthread+0x74/0x80 [ 1348.563294] [<c014e300>] ? kthread+0x0/0x80 [ 1348.563326] [<c0103c47>] ? kernel_thread_helper+0x7/0x10 [ 1348.563351] Code: 00 e8 73 4d 00 00 5d c3 90 55 89 e5 83 ec 10 89 5d f4 89 75 f8 89 7d fc 0f 1f 44 00 00 8b 3d c0 2e 67 c0 81 c7 fa 00 00 00 89 c3 <8b> 40 18 89 d6 85 c0 75 15 b8 ed ff ff ff 8b 5d f4 8b 75 f8 8b [ 1348.563528] EIP: [<c0393b02>] usb_lock_device_for_reset+0x22/0xd0 SS:ESP 0068:cf43ff38 [ 1348.563570] CR2: 000000005f7433e5 [ 1348.563593] ---[ end trace 9c3f1e3a2e5299d9 ]--- Signed-off-by: Max Vozeler <max@vozeler.com> Tested-by: Mark Wehby <MWehby@luxotticaRetail.com> Tested-by: Steven Harms <sharms@luxotticaRetail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-07-27Staging: usbip: fix multiple interfacesEndre Kollar
The stub_probe function instantiates an stub_dev object for all interfaces. Wich causes a problem. The stub_dev object belongs to their own interfaces. This patch creates the sdev object at the first stub_probe call, the other calls associate the interfaces to this.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
