# test inode item updating
|
|
#
|
|
# Our inode updating pattern involves updating in-memory inode
|
|
# structures and then explicitly migrating those to dirty persistent
|
|
# items. If we forget to update the persistent items then modifications
|
|
# to the in-memory inode can be lost as the inode is evicted.
|
|
#
|
|
# We test this by modifying inodes, unmounting, and comparing the
|
|
# mounted inodes to the inodes before the unmount.
