2010-10-15ubd: fix incorrect sector handling during request restartTejun Heo1-4/+5
Commit f81f2f7c (ubd: drop unnecessary rq->sector manipulation) dropped request->sector manipulation in preparation for global request handling cleanup; unfortunately, it incorrectly assumed that the updated sector wasn't being used. ubd tries to issue as many requests as possible to io_thread. When issuing fails due to memory pressure or other reasons, the device is put on the restart list and issuing stops. On IO completion, devices on the restart list are scanned and IO issuing is restarted. ubd issues IOs sg-by-sg and issuing can be stopped in the middle of a request, so each device on the restart queue needs to remember where to restart in its current request. ubd needs to keep track of the issue position itself because, * blk_rq_pos(req) is now updated by the block layer to keep track of _completion_ position. * Multiple io_req's for the current request may be in flight, so it's difficult to tell where blk_rq_pos(req) currently is. Add ubd->rq_pos to keep track of the issue position and use it to correctly restart io_req issue.

2010-09-29um: Proper Fix for f25c80a4: remove duplicate structure field initializationBoaz Harrosh1-14/+3
uml_net_set_mac() was broken and luckily it was never used, before. What it was trying to do is spin_lock before memcopy the mac address. Linus attempted to fix it in assumption that someone decided the lock was needed. But since it was never ever used at all, and was just dead code, I think we can assume that it is not needed, after all. On the other hand patch [f25c80a4] was trying to use eth_mac_addr() in eth_configure(), *which was the real fallout*. Because of state checks done inside eth_mac_addr() the address was never set. I have not reintroduced the memcpy wrapper, but I've put a comment for future cats. The code now is back to exactly as it was before [f25c80a4]. With the cleanup applied. If the spin_lock is indeed needed then a contender should supply a test case that fails, then fix it with the proper locking, as a separate unrelated patch.

2010-08-17Make do_execve() take a const filename pointerDavid Howells2-3/+6
Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.

2010-08-11dma-mapping: remove dma_is_consistent APIFUJITA Tomonori1-1/+0
Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

2010-08-07block: push down BKL into .open and .releaseArnd Bergmann1-1/+6
The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.

2010-07-27um: Convert to use read_persistent_clockJohn Stultz1-6/+7
This patch converts the um arch to use read_persistent_clock(). This allows it to avoid accessing xtime and wall_to_monotonic directly.

2010-07-27time: Kill off CONFIG_GENERIC_TIMEJohn Stultz1-4/+0
Now that all arches have been converted over to use generic time via clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME config option and simplify the generic code.

2010-07-21arch/um/drivers: remove duplicate structure field initializationJulia Lawall1-8/+2
There are two initializations of ndo_set_mac_address, one to a local function that is not used otherwise and one to a function that is defined elsewhere. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)<int(pr[0].line) or int(ps[0].column)<int(pr[0].column): cocci.print_main(fld,p0) // </smpl> akpm: - Use the standard eth_mac_addr() in uml_net_set_mac() - Remove unneeded and racy local set_ether_mac() - Remove duplicated (and incorrect) uml_netdev_ops.ndo_set_mac_address initializer. Fixes 8bb95b39a16ed55226810596f92216c53329d2fe ("uml: convert network device to netdevice ops").

2010-07-12sound: push BKL into open functionsArnd Bergmann1-0/+6
This moves the lock_kernel() call from soundcore_open to the individual OSS device drivers, where we can deal with it one driver at a time if needed, or just kill off the drivers. All core components in ALSA already provide adequate locking in their open()-functions and do not require the big kernel lock, so there is no need to add the BKL there.
