skb: Add inline helper for getting the skb end offset from head

2014-06-09T12:29:00Z

[ Upstream commit ec47ea82477404631d49b8e568c71826c9b663ac ] With the recent changes for how we compute the skb truesize it occurs to me we are probably going to have a lot of calls to skb_end_pointer - skb->head. Instead of running all over the place doing that it would make more sense to just make it a separate inline skb_end_offset(skb) that way we can return the correct value without having gcc having to do all the optimization to cancel out skb->head - skb->head.

ATM: Delete no use FILL_RX_POOLS_IN_BH marco

2011-07-08T16:06:31Z

The macro FILL_RX_POOLS_IN_BH is never been used, in order to avoid the compiler reports error because of the usage of function INIT_WORK, we just delete the marco. Cc: Chas Williams Cc: linux-atm-general@lists.sourceforge.net Signed-off-by: Wang Shaoyan Signed-off-by: David S. Miller

Madge Ambassador ATM Adapter driver: Always release_firmware() in ucode_init() and don't leak memory.

2011-01-09T23:45:48Z

Failure to call release_firmware() will result in memory leak in drivers/atm/ambassador.c::ucode_init(). This patch makes sure we always call release_firmware() when needed, thus removing the leak(s). Yes, I know checkpatch complains about this patch, but it was either that or completely mess up the existing style, so I opted to use the existing style and live with the checkpatch related flak.

atm: correct sysfs 'device' link creation and parent relationships

2010-12-10T23:45:05Z

The ATM subsystem was incorrectly creating the 'device' link for ATM nodes in sysfs. This led to incorrect device/parent relationships exposed by sysfs and udev. Instead of rolling the 'device' link by hand in the generic ATM code, pass each ATM driver's bus device down to the sysfs code and let sysfs do this stuff correctly.

atm: Convert pci_table entries to PCI_VDEVICE (if PCI_ANY_ID is used)

2010-07-16T02:05:18Z

This patch converts pci_table entries, where .subvendor=PCI_ANY_ID and .subdevice=PCI_ANY_ID, .class=0 and .class_mask=0, to use the PCI_VDEVICE macro, and thus improves readability. Signed-off-by: Peter Huewe Signed-off-by: David S. Miller

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

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.

net: Make setsockopt() optlen be unsigned.

2009-09-30T23:12:20Z

This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation.
