From 144d4899a3cdb9839d63fc71f9b5e599c213a805 Mon Sep 17 00:00:00 2001 From: Hubert Tong Date: Thu, 4 Apr 2019 00:40:34 +0000 Subject: [PATCH] [Support] On AIX, Check ENOTSUP on posix_fallocate instead of EOPNOTSUPP Summary: `posix_fallocate` can fail if the underlying filesystem does not support it; and, on AIX, such a failure is reported by a return value of `ENOTSUP`. The existing code checks only for `EOPNOTSUPP`, which may share the same value as `ENOTSUP`, but is not required to.
