Issue with testcases/kernel/fs/doio/rwtest

[cmcgcc]

Hello,

https://github.com/linux-test-project/ltp/blob/51b89954e538f5299821432c879ff1e23c596ad8/testcases/kernel/fs/doio/rwtest#L332 This line of rwtest clears dir and dfOpts options if it is a symlink because a symlink to busybox does not take options as described in the comments. But we see cases with a symlink to df.coreutils which works well with options. I think more granular check is needed like

-                        if test -h $(which df)
-                           then
-                               dir=""; dfOpts="";
-                        fi
+			if [[ "$(readlink -f "$(which df)")" == *"busybox"* ]]
+			then
+				dir=""; dfOpts="";
+			fi

Thanks
