Subject: btrfs: tree-log.c: Wrong printk information about namelen
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=286b92f43c0d0ae2c29a61769b66219fe5ae6701;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

btrfs: tree-log.c: Wrong printk information about namelen

In verify_dir_item, it wants to printk name_len of dir_item but
printk data_len acutally.

Fix it by calling btrfs_dir_name_len instead of btrfs_dir_data_len.
