# FS QA Test 474

# Inspired by syncfs bug of overlayfs which does not sync dirty inodes in
|
|
# underlying filesystem.
|
|
#
|
|
# Create a small file then run syncfs and shutdown filesystem(or underlying
|
|
# filesystem of overlayfs) to check syncfs result.
|
|
#
|
|
# Test will be skipped if filesystem(or underlying filesystem of overlayfs)
|
|
# does not support shutdown.
