Subject: [XFS] Fix barrier status change detection.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b5b8c9acd547244eb2b7d0280ba38b9dd01971cc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[XFS] Fix barrier status change detection.

The current code in xlog_iodone() uses the wrong macro to check if the
barrier has been cleared due to an EOPNOTSUPP error form the lower layer.
