Subject: xfs: fix unused log variable in xfs_log_cover()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4533fc631547213bd03fbdf0a96dd8eb6807d3a7;p=linux.git

xfs: fix unused log variable in xfs_log_cover()

The log variable is only used in kernels with asserts enabled.
Remove it and open code the dereference to avoid unused variable
warnings.
