| # 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. |
