From d564d2c4c2445cb0972453933dc87c2dcaac8597 Mon Sep 17 00:00:00 2001 From: ChenXiaoSong Date: Fri, 23 Sep 2022 13:40:15 +0800 Subject: NFSv4: check FMODE_EXEC from open context mode in nfs4_opendata_access() After converting file f_flags to open context mode by flags_to_mode(), open context mode will have FMODE_EXEC when file open for exec, so we check FMODE_EXEC from open context mode. No functional change, just simplify the code.
