f2fs: support configuring fault injection per superblock

2016-10-01T00:34:31+00:00

Previously, we only support global fault injection configuration, so that
when we configure type/rate of fault injection through sysfs, mount
option, it will influence all f2fs partition which is being used.

It is not make sence, since it will be not convenient if developer want
to test separated partitions with different fault injection rate/type
simultaneously, also it's not possible to enable fault injection in one
partition and disable fault injection in other one.

>From now on, we move global configuration of fault injection in module
into per-superblock, hence injection testing can be more flexible.

f2fs: avoid data race between FI_DIRTY_INODE flag and update_inode

2016-06-07T16:45:40+00:00

FI_DIRTY_INODE flag is not covered by inode page lock, so it can be unset
at any time like below.

Thread #1                        Thread #2
- lock_page(ipage)
- update i_fields
                                 - update i_size/i_blocks/and so on
				 - set FI_DIRTY_INODE
- reset FI_DIRTY_INODE
- set_page_dirty(ipage)

In this case, we can lose the latest i_field information.

f2fs: avoid unnecessary updating inode during fsync

2016-06-03T01:05:13+00:00

If roll-forward recovery can recover i_size, we don't need to update inode's
metadata during fsync.
