Subject: [PATCH AUTOSEL 4.9 09/21] ext4: fix incorrect inodes per group in error message

From: Josh Triplett <josh@...htriplett.org>

[ Upstream commit b9c538da4e52a7b79dfcf4cfa487c46125066dfb ]

If ext4_fill_super detects an invalid number of inodes per group, the
resulting error message printed the number of blocks per group, rather
than the number of inodes per group. Fix it to print the correct value.

Fixes: cd6bb35bf7f6d ("ext4: use more strict checks for inodes_per_block on mount")
