Subject: xfs: pass current lsn to log recovery buffer validation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22db9af2488655f7f841e9588d25384a5e694fa6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

xfs: pass current lsn to log recovery buffer validation

The current LSN must be available to the buffer validation function to
provide the ability to update the metadata LSN of the buffer. Pass the
current_lsn value down to xlog_recover_validate_buf_type() in
preparation.
