Hi,
This is another set of independent patches. The only connection
between them is that they try to address problems spotted by proposed
coccinelle semantic patch assign_signed_to_unsigned.cocci[1].
This semantic patch tries to find bugs, where signed result of function
is lost due to conversion to unsigned value. To decrease number of
false positives it looks if after the call there is comparison of
the result variable with 0.
In pseudo-code it looks like:
unsigned = signed_function(...);
...
if (unsigned ( < | <= ) 0 )
...
This patchset contains mainly real bug fixes. Only last three patches
do not fix real bugs, they just proposes change of types to avoid
conversions int -> unsigned.
The patches are based on linux-next.
