Fabio M. De Francesco f451fd97dd ext4: drop the call to ext4_error() from ext4_get_group_info() ... A recent patch added a call to ext4_error() which is problematic since some callers of the ext4_get_group_info() function may be holding a spinlock, whereas ext4_error() must never be called in atomic context. This triggered a report from Syzbot: "BUG: sleeping function called from invalid context in ext4_update_super" (see the link below). Therefore, drop the call to ext4_error() from ext4_get_group_info(). In the meantime use eight characters tabs instead of nine characters ones.
