It seems strchr() and strrchr() are used more often than index() and
rindex(). Therefore, simply migrate all kernel code to use it.
For the XFS code, remove an empty line to make the code identical to
the code in the Linux kernel.
among other things, the DEVFS rule subsystem to match nodes against a
path pattern supplied by the user.
fnmatch.c was repo-copied from src/lib/libc/gen/fnmatch.c, and the
only changes to it are those necessary to make it compile in the
kernel. The relevant parts of fnmatch.h were imported into libkern.h.
Approved by: -arch
and FNM_LEADING_DIR were specified and the pattern ended with "*".
Example: pattern="src/usr.sbin/w*", string="src/usr.sbin/watch/watch.8,v".
This should match, but did not.
1) Rename FNM_ICASE to FNM_CASEFOLD
2) Add FNM_LEADING_DIR
Add proper (unsigned char) casts to tolower().
Use 'char' function argument for proper sign extension
