Hi,
Here's v7 of the tunables patchset. Changes are as follows:
- Fixed up issues that Florian pointed out
- Replaced mmap call with an INTERNAL_SYSCALL to avoid setting errno
- Dropped the call to __getpagesize since the kernel is capable of
rounding requests to nearest page size
I tried to avoid the copying of the tunables string, but it complicated the
tunables interface by introducing a length attribute for strings so I dropped
that idea.
Tested on x86_64.
Siddhesh Poyarekar (4):
Add framework for tunables
Initialize tunable list with the GLIBC_TUNABLES environment variable
Enhance --enable-tunables to select tunables frontend at build time
