lib: vsprintf: useless strlen() removed

2010-08-10T03:45:09Z

The strict_strtoul() and strict_strtoull() functions used strlen() to check argument's length in a situation where it wasn't strictly necessary Signed-off-by: Michal Nazarewicz Cc: "Yi Yang" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

vsprintf: Recursive vsnprintf: Add "%pV", struct va_format

2010-07-04T17:40:17Z

Add the ability to print a format and va_list from a structure pointer Allows __dev_printk to be implemented as a single printk while minimizing string space duplication. %pV should not be used without some mechanism to verify the format and argument use ala __attribute__(format (printf(...))).

kernel-wide: replace USHORT_MAX, SHORT_MAX and SHORT_MIN with USHRT_MAX, SHRT_MAX and SHRT_MIN

2010-05-25T15:07:02Z

- C99 knows about USHRT_MAX/SHRT_MAX/SHRT_MIN, not USHORT_MAX/SHORT_MAX/SHORT_MIN. - Make SHRT_MIN of type s16, not int, for consistency.

lib/vsprintf.c: add missing EXPORT_SYMBOL(simple_strtoll)

Add a missing EXPORT_SYMBOL. I must be the first person that wants to use this function :-) Signed-off-by: Hans Verkuil Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

vsprintf: Change struct printf_spec.precision from s8 to s16

2010-04-14T17:32:35Z

Commit ef0658f3de484bf9b173639cd47544584e01efa5 changed precision from int to s8. There is existing kernel code that uses a larger precision. An example from the audit code: vsnprintf(...,..., " msg='%.1024s'", (char *)data); which overflows precision and truncates to nothing. Extending precision size fixes the audit system issue. Other changes: Change the size of the struct printf_spec.type from u16 to u8 so sizeof(struct printf_spec) stays as small as possible. Reorder the struct members so sizeof(struct printf_spec) remains 64 bits without alignment holes. Document the struct members a bit more.

resource: add window support

2010-03-15T00:08:36Z

Add support for resource windows. This is for bridge resources, i.e., regions where a bridge forwards transactions from the primary to the secondary side. Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown

resource: add bus number support

2010-03-15T00:08:35Z

Add support for bus number resources. This is for bridges with a range of bus numbers behind them. Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown

vsprintf: move %pR resource printf_specs off the stack

2010-03-07T01:53:07Z

This adds separate I/O and memory specs, so we don't have to change the field width in a shared spec, which then lets us make all the specs const and static, since they never change. Signed-off-by: Bjorn Helgaas Signed-off-by: Linus Torvalds

vsprintf: clarify comments for printf_spec flags
