Subject: [PATCH] ext4: Fix mount failure with quota configured as module
Date: Fri, 21 Feb 2020 11:08:35 +0100	[thread overview]
Message-ID: <> (raw)

When CONFIG_QFMT_V2 is configured as a module, the test in
ext4_feature_set_ok() fails and so mount of filesystems with quota or
project features fails. Fix the test to use IS_ENABLED macro which works
properly even for modules.

Fixes: d65d87a07476 ("ext4: improve explanation of a mount failure caused by a misconfigured kernel")
