Adhemerval Zanella edcda4c08a mips: Do not malloc on getdents64 fallback ... This patch changes how the fallback getdents64 implementation calls non-LFS getdents by replacing the scratch_buffer with static buffer plus a loop on getdents calls. This avoids the potential malloc call on scratch_buffer_set_array_size for large input buffer size at the cost of more getdents syscalls. It also adds a small optimization for older kernels, where the first ENOSYS failure for getdents64 disable subsequent calls. Check the dirent tests on a mips64-linux-gnu with getdents64 code disabled. * sysdeps/unix/sysv/linux/mips/mips64/getdents64.c (__getdents64): Add small optimization for older kernel to avoid issuing __NR_getdents64 on each call and replace scratch_buffer usage with a static allocated buffer.
