Subject: [PATCH 1/2] f2fs: fix dcache lookup of !casefolded directories

From: Eric Biggers <>

Do the name comparison for non-casefolded directories correctly.

This is analogous to ext4's commit 66883da1eee8 ("ext4: fix dcache
lookup of !casefolded directories").

Fixes: 2c2eb7a300cd ("f2fs: Support case-insensitive file name lookups")
Cc: <> # v5.4+
