Hi,
Here is an updated version of the glibc tunables patchset.
Changes:
- Use sbrk instead of mmap for allocation of the tunables string and add a
note about setting errno. I'll post a patch to add an __sbrk_noerrno in
2.26 to make this bullet-proof.
- Go back to __builtin_unreachable because __builtin_trap may cause issues in
other architectures. I will do a build test of other architectures and post
an update before release if everything is OK.
- Fixed up manual changes, including ones that Rical had suggested earlier - I
had made those in another branch and forgotten about them.
