* checkpatch: if should not continue a preceeding braceAndy Whitcroft2009-01-15
| | | | | | | | | | | | | | We should not be continuing a braced section with an if, for example: if (...) { } if (...) { } Detect this and suggest adding a newline.

* checkpatch: allow parentheses on return handle array valuesAndy Whitcroft2009-01-15
| | | | | | | | | | When we allow return to have surrounding parentheses when containing comparison operators we are not correctly handling the case where the values contain array sufffixes.

* checkpatch: type/cast spacing should not check prefix spacingAndy Whitcroft2009-01-15
| | | | | | | | | | We should not be complaining about the prefix spacing for types and casts. We are triggering here because the check for spacing between '*'s is overly loose. Tighten this up.

* checkpatch: handle missing #if open in contextAndy Whitcroft2009-01-15
| | | | | | | | | | | | If the #if opening statement is not in the context then the context stack can be empty. Handle this by ensuring there is always a blank entry in the stack.

* checkpatch: ensure we actually detect if assignments split across linesAndy Whitcroft2009-01-06
| | | | | | | | | | | When checking for assignments within if conditionals we check the whole of the condition, but the match is performed using a line constrained regular expression. This means we can miss split conditionals or those on the second line. Allow the check to span lines.

* checkpatch: fix continuation detection when handling spacing on operatorsAndy Whitcroft2009-01-06

* checkpatch: try to catch missing VMLINUX_SYMBOL() in vmlinux.lds.hMike Frysinger2009-01-06
| | | | | | | | | | | | | Seems like every other release we have someone who updates vmlinux.lds.h and adds C-visible symbols without VMLINUX_SYMBOL() around them. So start checking the file and reject assignments which have plain symbols on either side.

* checkpatch: Add warning for p0-patchesWolfram Sang2009-01-06
| | | | | | | | | | | | | | | | Some people work internally with -p0-patches which has the danger that one forgets to convert them to -p1 before mainlining. Bitten myself and seen p0-patches in mailing lists occasionally, this patch adds a warning to checkpatch.pl in case a patch is -p0. If you really want, you can fool this check to generate false positives, this is why it just spits a warning. Making the check 100% proof is trickier than it looks, so let's start with a version which catches the cases of real use.

| | | | | | | | | | | | | | | Disallow spaces within multiple pointer stars (*) in both casts and definitions.

* checkpatch: comment ends inside strings is most likely not an open commentAndy Whitcroft2009-01-06
| | | | | | | | | | | | | | When we are detecting whether a comment is open when we start a hunk we check for the first comment edge in the hunk and assume its inverse. However if the hunk contains something like below, then we will assume that a comment was open. Update this heuristic to see if the comment edge is obviously within double quotes and ignore it if so: foo(" */); Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | When reporting some complex trailing statements we report only the starting line of the error, that tends to imply the shown line is in error and confuse the reader.
