Leon Romanovsky 9836b8b949 f2fs: unify string length declarations and usage
This patch is intended to unify string length declarations and usage.
There are number of calls to strlen which return size_t object.
The size of this object depends on compiler if it will be bigger,
equal or even smaller than an unsigned int

Jaegeuk Kim 1efef83202 f2fs: do f2fs_balance_fs in front of dir operations
In order to conserve free sections to deal with the worst-case scenarios, f2fs
should be able to freeze all the directory operations especially when there are
not enough free sections. The f2fs_balance_fs() is for this use.

When FS utilization becomes almost 100%, directory operations can be failed due
to -ENOSPC frequently, which produces some dirty node pages occasionally.

Previously, in such a case, f2fs_balance_fs() is not able to be triggered since
it is triggered only if the directory operation ends up with success.

So, this patch triggers f2fs_balance_fs() at first before handling directory
operations.

Namjae Jeon a0d42539e1 f2fs: make use of GFP_F2FS_ZERO for setting gfp_mask
Since, GFP_NOFS and __GFP_ZERO is being used to set gfp_mask.
We can instead make use of already predefined macro GFP_F2FS_ZERO.

Namjae Jeon 61412b64b9 f2fs: move error condition for mkdir at proper place
In function f2fs_mkdir, err is being initialized without even checking
if there was any error in new inode creation. So, instead check the
inode error and make use of error/return condition.

Jaegeuk Kim 0a8165d7c2 f2fs: adjust kernel coding style
As pointed out by Randy Dunlap, this patch removes all usage of "/**" for comment
blocks. Instead, just use "/*".
