Subject: f2fs: fix to convert inline inode in ->setattr
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0cab80ee0c9e17337468c4c0f96786ccbca693d9;p=linux-beck.git

f2fs: fix to convert inline inode in ->setattr

In commit 3c4541452748 ("f2fs: do not trim preallocated blocks when
truncating after i_size"), in order to follow the regulation: "truncate(x)
where x > i_size will not trim all blocks past i_size." like other file
systems, in ->setattr we invoked truncate_setsize instead of f2fs_truncate
to avoid unneeded block trimming in such case, but forgot to call
f2fs_convert_inline_inode keep consistency of inline data conversion rule.

This patch fixes to convert inline data if necessary.
