[PATCH] reiserfs: fix journaling issue regarding fsync()
When write() extends a file(i_size is increased) and fsync() is called, change of inode must be written to journaling area through fsync(). But,currently the i_trans_id is not correctly updated when i_size is increased. So fsync() does not kick the journal writer. Reiserfs_file_write() already updates the transaction when blocks are allocated, but the case when i_size increases and new blocks are not added is not correctly treated. Following patch fix this bug.
