Re: Remove pre-2.4.1 Linux kernel support
On 07/12/2012 01:48 AM, Joseph S. Myers wrote:
This patch continues the cleanup of support for old kernel versions by
making the minimum kernel version 2.4.1 (which for many conditionals
actually means 2.4.0 final release, for features introduced in
2.4.0-testN kernels). Macros that are no longer needed are removed.
__ASSUME_GETDENTS64_SYSCALL is defined unconditionally to 1 in
kernel-features.h, rather than removed, since the MIPS version
undefines it for n32 ABI for kernel versions before 2.6.35.
Tested x86 and x86_64.
The intended next step is moving the kernel version requirement from
2.4.1 to 2.4.21 (which will eliminate almost all the remaining
conditionals on particular 2.4.x versions), after which I'll look
again carefully at the macros defined independently of kernel version
but for certain architectures only, to see if any more of them can be
eliminated before moving the version requirement to 2.6.0 (then
2.6.16, then 2.6.16-final).

This looks fine, thanks,
