There are at least two bug reports of kernel tree-checker complaining about invalid inode generation. All offending inodes seem to be caused by old kernel around 2014, with inode generation overflow. So add such check and repair ability to lowmem mode check first. This involves: - Calculate the inode generation upper limit If it's an inode from log tree, then the upper limit is super_generation + 1, otherwise it's super_generation. - Check if the inode generation is larger than the upper limit - Repair by resetting inode generation to current transaction generation Reported-by: Charles Wright <charles.v.wright@gmail.com> Tested-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |
