Name:private llseek:* for a block special file file_inode(file)->i_size is zero* so we compute the size by hand (just as in block_read/write above)
Proto:static loff_t block_llseek(struct file *file, loff_t offset, int whence)
Type:loff_t
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct file * | file | |
| loff_t | offset | |
| int | whence |
| 651 | bd_inode = bdev_file_inode(file) |
| 654 | inode_lock(bd_inode) |
| 655 | retval = xed_size_llseek - llseek implementation for fixed-sized devices*@file: file structure to seek on*@offset: file offset to seek to*@whence: type of seek*@size: size of the file |
| 656 | inode_unlock(bd_inode) |
| 657 | Return retval |
