Subject: [PATCH 2/2] ext4: clean up feature flag checking and usage
Clean up the EXT4_{HAS,SET,CLEAR}_{,RO_,IN}COMPAT_FEATURE() flag
checking to be easier to read, as well as safer from accidental
coding mistakes. Instead of passing the EXT4_FEATURE_*COMPAT_foo
flag name to the macro, generate the EXT4_FEATURE_*COMPAT prefix
within the macro, to ensure the flag name matches the check being
done, since the numerical value might be for the wrong compat type.
