Subject[PATCH v2 2/2] NFSv4: check FMODE_EXEC from open context mode in nfs4_opendata_access()
Date
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.
