f2fs: add F2FS_INLINE_DOTS to recover missing dot dentries

2015-04-10T22:08:57+00:00

If f2fs was corrupted with missing dot dentries, it needs to recover them after
fsck.f2fs detection.

The underlying precedure is:

1. The fsck.f2fs remains F2FS_INLINE_DOTS flag in directory inode, if it detects
missing dot dentries.

2. When f2fs looks up the corrupted directory, it triggers f2fs_add_link with
proper inode numbers and their dot and dotdot names.

3. Once f2fs recovers the directory without errors, it removes F2FS_INLINE_DOTS
finally.

f2fs: fix to calculate max length of contiguous free slots correctly

2015-04-10T22:08:40+00:00

When lookuping for creating, we will try to record the level of current dentry
hash table if current dentry has enough contiguous slots for storing name of new
file which will be created later, this can save our lookup time when add a link
into parent dir.

But currently in find_target_dentry, our current length of contiguous free slots
is not calculated correctly. This make us leaving some holes in dentry block
occasionally, it wastes our space of dentry block.

Let's refactor the lookup flow for max slots as following to fix this issue:
a) increase max_len if current slot is free;
b) update max_slots with max_len if max_len is larger than max_slots;
c) reset max_len to zero if current slot is not free.

f2fs: remove unnecessary condition judgment

2015-04-10T22:08:38+00:00

Remove the unnecessary condition judgment, because
'max_slots' has been initialized to '0' at the beginging
of the function, as following:
if (max_slots)
       *max_slots = 0;

f2fs: set the correct place of initializing *res_page

2015-04-10T22:08:37+00:00

The function 'find_in_inline_dir()' contain 'res_page'
as an argument. So, we should initiaize 'res_page' before
this function.

f2fs: remove pointless bit testing in f2fs_delete_entry()

2014-11-04T00:07:38+00:00

There's no point in using test_and_clear_bit_le() when we don't use the
return value of the function. Just use clear_bit_le() instead.
