include/linux/ctype.h: make isdigit() table lookupless

2016-10-11T22:06:30Z

Make isdigit into a simple range checking inline function: return '0' <= c && c <= '9'; This code is 1 branch, not 2 because any reasonable compiler can optimize this code into SUB+CMP, so the code while (isdigit((c = *s++))) ... remains 1 branch per iteration HOWEVER it suddenly doesn't do table lookup priming cacheline nobody cares about.

lib, net: make isodigit() public and use it

2013-04-30T01:28:19Z

There are at least two users of isodigit(). Let's make it a public function of ctype.h. Signed-off-by: Andy Shevchenko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lib: make _tolower() public

2011-07-26T03:57:16Z

This function is required by *printf and kstrto* functions that are located in the different modules. This patch makes _tolower() public. However, it's good idea to not use the helper outside of mentioned functions.

string: factorize skip_spaces and export it to be generally available

2009-12-15T16:53:32Z

On the following sentence: while (*s && isspace(*s)) s++; If *s == 0, isspace() evaluates to ((_ctype[*s] & 0x20) != 0), which evaluates to ((0x08 & 0x20) != 0) which equals to 0 as well. If *s == 1, we depend on isspace() result anyway. In other words, "a char equals zero is never a space", so remove this check. Also, *s != 0 is most common case (non-null string). Fixed const return as noticed by Jan Engelhardt and James Bottomley. Fixed unnecessary extra cast on strstrip() as noticed by Jan Engelhardt.

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
