That's designed to avoid checking overlapping part of a leaf.

item of the first inode(256) is missing.
So above traversal will check from inode 257 and found nothing wrong.

The fix is done in 2 part:
1) Manually check the first inode
   To avoid case like fsck/010

2) Check inode if ino changes from the first ino of a leaf

btrfs-progs: check: skip shared node or leaf check for low_memory mode

The basic idea is simple. Assume a middle tree node A is shared and
its referencing fs/file tree root ids are 5, 258 and 260, then we
only check node A in the tree who has the smallest root id. That means
in this case, when checking root tree(5), we check inode A, for root
tree 258 and 260, we can just skip it.

Notice even with this patch, we still may visit a shared node or leaf
multiple times. This happens when a inode metadata occupies multiple
leaves.

                 leaf_A     leaf_B
When checking inode item in leaf_A, assume inode[512] have file extents
in leaf_B, and leaf_B is shared. In the case, for inode[512], we must
visit leaf_B to have inode item checked. After finishing inode[512] check,
here we walk down tree root to leaf_B to check whether node or leaf
is shared, if some node or leaf is shared, we can just skip it and below
nodes or leaf's check.

I also fill a disk partition with linux source codes and create 3
snapshots in it. Before this patch, it averagely took 46s to finish one
btrfsck execution, with this patch, it averagely took 15s.

7 years agobtrfs-progs: return best entry, if it is the first one

btrfs-progs: return best entry, if it is the first one

The find_most_right_entry() tends to miss on the best entry if it is the
first one on the list and there are only two entries in the list.  So,
we assign both prev and best to entry.

To do this, the selection process (rather the rejection) has to be
performed earlier to skip on broken==count.

7 years agobtrfs-progs: utils: Fix NULL pointer derefernces in string_is_numerical

btrfs-progs: utils: Fix NULL pointer derefernces in string_is_numerical

In get_running_kernel_version() function, we directly pass return
pointer from strtok_r() to string_is_numerical().

Return pointer from strok_r() can be NULL, but string_is_numerical()
can't handle it and will cause NULL pointer derefernces.

Fix it by check if it's a NULL pointer first.
