f2fs: fix wrong casting for dentry name

2014-08-29T07:26:50+00:00

The dentry name type is unsigned char *.
If we don't match this type, some character codes can be changed by signed bit.

f2fs: unify string length declarations and usage

2012-12-28T02:27:53+00:00

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

f2fs: fix up f2fs_get_parent issue to retrieve correct parent inode number

2012-12-26T01:39:52+00:00

Test Case:
[NFS Client]
ls -lR .

[NFS Server]
while [ 1 ]
do
echo 3 > /proc/sys/vm/drop_caches
done

Error on NFS Client: "No such file or directory"

When cache is dropped at the server, it results in lookup failure at the
NFS client due to non-connection with the parent. The default path is it
initiates a lookup by calculating the hash value for the name, even though
the hash values stored on the disk for "." and ".." is maintained as zero,
which results in failure from find_in_block due to not matching HASH values.
Fix up, by using the correct hashing values for these entries.

f2fs: fix endian conversion bugs reported by sparse

2012-12-11T04:43:42+00:00

This patch should resolve the bugs reported by the sparse tool.
Initial reports were written by "kbuild test robot" managed by fengguang.wu.

In my local machines, I've tested also by running:
> make C=2 CF="-D__CHECK_ENDIAN__"

Accordingly, I've found lots of warnings and bugs related to the endian
conversion. And I've fixed all at this moment.
