Subject: [PATCH] ext4: actually request zeroing of inode table after grow
Git-commit: 310a997fd74de778b9a4848a64be9cda9f18764a
Patch-mainline: v5.2-rc1
References: bsc#1135315
It is never possible, that number of block groups decreases,
since only online grow is supported.
But after a growing occured, we have to zero inode tables
for just created new block groups.
Fixes: 19c5246d2516 ("ext4: add new online resize interface")
