-Subject: [PATCH] Revert "Set FD_CLOEXEC on opened files before exec from lua
- script is called"
-
-This reverts commit 7a7c31f551ff167f8718aea6d5048f6288d60205.
-The reason is that when _SC_OPEN_MAX is much higher than the usual 1024
-(for example inside docker), the performance drops sharply.
-
-Upstream has been notified:
-https://bugzilla.redhat.com/show_bug.cgi?id=1537564
-
-Upstream-Status: Inappropriate [upstream needs to come up with a better fix]
