Subject: Re: [PATCH v2 2/3] ext4: fix the parsing of empty string mount
 parameters


hi, Luis Henriques,

we noticed in
https://lore.kernel.org/all/20240307160225.23841-1-lhenriques@suse.de/
it was mentioned this patch is for "ext4/053 fstest failure",
however, in our tests, 053 can pass on parent but fail on this commit.

not sure if there is a xfstests patch works with this patch? Thanks!

below report just FYI.
