Subject: ext4: Display the mballoc flags in mb_history in hex instead of decimal
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ef90db93a4ddfc300af288c2a1bfc1e6c79da64;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ext4: Display the mballoc flags in mb_history in hex instead of decimal

Displaying the flags in base 16 makes it easier to see which flags
have been set.
