# FS QA Test 002
|
||
|
|
#
|
||
|
|
# Test that calling fsync against a file using the merged directory does not
|
||
|
|
# result in a crash nor fails unexpectedly.
|
||
|
|
#
|
||
|
|
# This is motivated by a change in overlayfs that resulted in a crash (invalid
|
||
|
|
# memory access) when the lower or upper directory belonged to a btrfs file
|
||
|
|
# system.
