# Test Case: Dotdot Entry Handling
|
|
|
|
**Test ID**: TC050-dotdot-handling
|
|
**Category**: Directory Operations
|
|
**Priority**: High
|
|
|
|
## Objective
|
|
|
|
Verify dotdot is returned and resolves nested paths to the correct parent
|
|
vnode without lock-order failure.
|
|
|
|
## Procedure
|
|
|
|
Mount vfs/vfs-plain.erofs and run:
|
|
|
|
./readdir_probe /tmp/repo22-g3/mnt/parent/child 128
|
|
stat -f '%i %HT' /tmp/repo22-g3/mnt/parent
|
|
stat -f '%i %HT' /tmp/repo22-g3/mnt/parent/child/..
|
|
cmp fixtures/vfs/source/parent/file.txt \
|
|
/tmp/repo22-g3/mnt/parent/child/grandchild/../../file.txt
|
|
|
|
## Expected Results
|
|
|
|
The traversal contains one dotdot DT_DIR entry, both parent stat commands
|
|
report the same NID, and multiple dotdot components reach the expected file.
|
|
Record output, dmesg delta, and cleanup.
