f2fs: fix to recover converted inline_data

2014-11-26T02:08:00+00:00

If an inode has converted inline_data which was written to the disk, we should
set its inode flag for further fsync so that this inline_data can be recovered
from sudden power off.

f2fs: convert inline_data when i_size becomes large

2014-11-11T22:16:12+00:00

If i_size becomes large outside of MAX_INLINE_DATA, we shoud convert the inode.
Otherwise, we can make some dirty pages during the truncation, and those pages
will be written through f2fs_write_data_page.
At that moment, the inode has still inline_data, so that it tries to write non-
zero pages into inline_data area.

f2fs: reduce the number of inline_data inode before clearing it

2014-11-11T00:29:14+00:00

The # of inline_data inode is decreased only when it has inline_data.
After clearing the flag, we can't decreased the number.

f2fs: revisit inline_data to avoid data races and potential bugs

2014-11-05T01:34:11+00:00

This patch simplifies the inline_data usage with the following rule.
1. inline_data is set during the file creation.
2. If new data is requested to be written ranges out of inline_data,
 f2fs converts that inode permanently.
3. There is no cases which converts non-inline_data inode to inline_data.
4. The inline_data flag should be changed under inode page lock.
