Subject: xfs: call roundup_64() to calculate the min_logblks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2c2bcc0735f4ab052559b539f3fcab4087187232;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

xfs: call roundup_64() to calculate the min_logblks

Replace roundup() with roundup_64() as we calculate min_logblks
with 64-bit divisions.  Hence, call roundup() will cause the
following error while compiling a 32-bit kernel:

fs/built-in.o: In function `xfs_log_calc_minimum_size':
fs/xfs/xfs_log_rlimit.c:140: undefined reference to `__udivdi3'
