Naked use sscanf can be troublesome because the pointed to variables may not have been set. Add a warning when the sscanf return value is not used. For now, do not add __must_check to the sscanf prototype because that will cause a couple of hundred new warnings when compiling a kernel. Signed-off-by:

Avoid prescribing kernel styled shortcuts for gcc extensions of __attribute__((foo)) in the uapi include paths. Fix $realfile filename when using -f/--file to not remove first level directory as if the filename was used in a -P1 patch. Only strip the first level directory (typically a or b) for P1 patches.

Find a few more cases where parentheses are used around the value of a return statement. This now uses the "$balanced_parens" test and also makes the test depend on perl v5.10 and higher. This now finds return with parenthesis uses the old code did not find like: ERROR: return is not a function, parentheses are not required #211: FILE: arch/m68k/include/asm/sun3xflop.h:211: + return ((error == 0) ? 0 : -1); Signed-off-by:

Kernel maintainers reject new instances of the GPL boilerplate paragraph directing people to write to the FSF for a copy of the GPL, since the FSF has moved in the past and may do so again. Make this an error for new code, but just a --strict CHK in --file mode; anyone interested in doing tree-wide cleanups of this form can enable this test explicitly. Signed-off-by:

Peter Zijlstra prefers that comments be required near uses of memory barriers. Change the message level for memory barrier uses from a --strict test only to a normal WARN so it's always emitted. This might produce false positives around insertions of memory barriers when a comment is outside the patch context block. And checkpatch is still stupid, it only looks for existence of any comment, not at the comment content. Signed-off-by:

People get this regularly wrong and it breaks the LTO builds, as it causes a section attribute conflict. Add --fix capability too. Based on a patch from Andi Kleen. Signed-off-by:

seq_vprintf, seq_printf and seq_puts are logging functions and should be allowed to exceed the maximium line length. Add maximum line length exceptions for these functions. Also, suggesting seq_printf conversions to seq_puts should be tested for arguments after the format. Signed-off-by:

Extend the CamelCase words found to include structure members. In https://lkml.org/lkml/2013/9/3/318 Sarah Sharp (mostly) wrote: "In general, if checkpatch.pl complains about a variable a patch introduces that's CamelCase, you should pay attention to it. Otherwise, [] ignore it." So, if checking a patch, scan the original patched file if it's available and add any preexisting CamelCase types so reuses do not generate CamelCase messages. That also means Andrew's not so cruelly spurned anymore. https://lkml.org/lkml/2013/2/22/426Signed-off-by:

Spaces around trigraphs are specified by CodingStyle but checkpatch is currently silent about them because there are many current instances without them. Make missing spaces around trigraphs a --strict message. Signed-off-by:

We already have list_first_entry(), it makes sense to also add list_last_entry() for consistency. And we use both helpers in list_for_each_*(). Signed-off-by:

Oleg Nesterov authored
Now that we have list_{next,prev}_entry() we can change list_for_each_entry*() and list_safe_reset_next() to use the new helpers to improve the readability. Signed-off-by: -
Oleg Nesterov authored
Add two trivial helpers list_next_entry() and list_prev_entry(), they can have a lot of users including list.h itself. In fact the 1st one is already defined in events/core.c and bnx2x_sp.c, so the patch simply moves the definition to list.h. Signed-off-by:

When using pool space for DMA buffer, there might be duplicated calling of gen_pool_alloc() and gen_pool_virt_to_phys() in each implementation. Thus it's better to add a simple helper function, a compatible one to the common dma_alloc_coherent(), to save some code. Signed-off-by:
