If anyone has any objections, please let me know. ------------------ From: Zhang Yi [ Upstream commit 68ee261fb15457ecb17e3683cb4e6a4792ca5b71 ] If one group is marked as block bitmap corrupted, its free blocks cannot be used and its free count is also deducted from the global sbi->s_freeclusters_counter. User might be confused about the absent free space because we can't query the information about corrupted block groups except unreliable error messages in syslog. So add a hint to show block bitmap corrupted groups in mb_groups.
