# Test some small truncations to check inline_data and its cached data are
|
|
# truncated correctly at the same time.
|
|
#
|
|
# The inline_data feature was introduced in ext4 and f2fs as follows.
|
|
# ext4 : http://lwn.net/Articles/468678/
|
|
# f2fs : http://lwn.net/Articles/573408/
|
|
#
|
|
# The basic idea is embedding small-sized file's data into relatively large
|
|
# inode space.
|
|
# In ext4, up to 132 bytes of data can be stored in 256 bytes-sized inode.
|
|
# In f2fs, up to 3.4KB of data can be embedded into 4KB-sized inode block.
