+# FS QA Test No. f2fs/001
+#
+# Test inline_data behaviors when filesystem is full.
+#
+# 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.
