函数名称:Check that the two inodes are eligible for cloning, the ranges make* sense, and then flush all dirty data. Caller must ensure that the* inodes have been locked against any other modifications.
函数原型:int generic_remap_file_range_prep(struct file *file_in, loff_t pos_in, struct file *file_out, loff_t pos_out, loff_t *len, unsigned int remap_flags)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct file * | file_in | |
loff_t | pos_in | |
struct file * | file_out | |
loff_t | pos_out | |
loff_t * | len | |
unsigned int | remap_flags |
1948 | inode_in等于file_inode(file_in) |
1949 | inode_out等于file_inode(file_out) |
1950 | same_inode等于inode_in恒等于inode_out |
1954 | 如果IS_IMMUTABLE(inode_out)则返回:负EPERM |
1957 | 如果IS_SWAPFILE(inode_in)或IS_SWAPFILE(inode_out)则返回:负ETXTBSY |
1967 | 如果len恒等于0则 |
1975 | 如果len恒等于0则返回:0 |
1986 | inode_dio_wait(inode_in) |
1987 | 如果非same_inode则inode_dio_wait(inode_out) |
2004 | bool is_same = false |
