f2fs: handle errors correctly during f2fs_reserve_block The get_dnode_of_data nullifies inode and node page when error is occurred. There are two cases that passes inode page into get_dnode_of_data(). 1. make_empty_dir() -> get_new_data_page() -> f2fs_reserve_block(ipage) -> get_dnode_of_data() 2. f2fs_convert_inline_data() -> __f2fs_convert_inline_data() -> f2fs_reserve_block(ipage) -> get_dnode_of_data() This patch adds correct error handling codes when get_dnode_of_data() returns an error. At first, f2fs_reserve_block() calls f2fs_put_dnode() whenever reserve_new_block returns an error. So, the rule of f2fs_reserve_block() is to nullify inode page when there is any error internally. Finally, two callers of f2fs_reserve_block() should call f2fs_put_dnode() appropriately if they got an error since successful f2fs_reserve_block().

This patch refactors f2fs_convert_inline_data to check a couple of conditions internally for deciding whether it needs to convert inline_data or not. So, the new f2fs_convert_inline_data initially checks: 1) f2fs_has_inline_data(), and 2) the data size to be changed. If the inode has inline_data but the size to fill is less than MAX_INLINE_DATA, then we don't need to convert the inline_data with data allocation.

f2fs: fix to truncate inline data in inode page when setattr Previous we do not truncate inline data in inode page when setattr, so following case could still read the inline data which has already truncated: 1.write inline data 2.ftruncate size to 0 3.ftruncate size to max inline data size 4.read from offset 0 This patch introduces truncate_inline_data() to fix this problem. change log from v1: o fix a bug and do not truncate first page data after truncate inline data.
