From 5941e7f092233adb5415b2a12addea48a97a6618 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Thu, 30 Apr 2026 18:44:38 +0900 Subject: [PATCH] Fix errno check based on EINTR in pg_flush_data() Upon a failure of sync_file_range(), EINTR was checked based on the returned result of the routine rather than its errno. sync_file_range() returns -1 on failure, making the check a no-op, invalidating the retry attempt in this case. Oversight in 0d369ac65004.
