Subject: [PATCH 13/22] bfs_add_entry(): get rid of pointless ->d_name.len checks
Date: Wed, 20 Dec 2023 05:25:36 +0000 [thread overview]
Message-ID: <20231220052536.GL1674809@ZenIV> (raw)
In-Reply-To: <20231220051348.GY1674809@ZenIV>
First of all, any dentry getting here would have passed bfs_lookup(),
so it it passed ENAMETOOLONG check there, there's no need to
repeat it. And we are not going to get dentries with zero name length -
that check ultimately comes from ext2 and it's as pointless here as it
used to be there.
