Subject: f2fs: fix dcache lookup of !casefolded directories
From: Eric Biggers <ebiggers@xxxxxxxxxx>
commit 5515eae647426169e4b7969271fb207881eba7f6 upstream.
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")
