名称	描述
generic_file_read_iter	generic_file_read_iter - generic filesystem read routine@iocb: kernel I/O control block@iter: destination for the data read* This is the "read_iter()" routine for all filesystems* that can use the page cache directly
generic_file_direct_write
__generic_file_write_iter	__generic_file_write_iter - write data to a file@iocb: IO state structure (file, offset, etc.)@from: iov_iter with data to write* This function does all the work needed for actually writing data to a* file
generic_remap_file_range_prep	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.
do_blockdev_direct_IO	This is a library function for use by filesystem drivers
iomap_dio_rw	map_dio_rw() always completes O_[D]SYNC writes regardless of whether the IO* is being issued as AIO or not. This allows us to optimise pure data writes* to use REQ_FUA rather than requiring generic_write_sync() to issue a* REQ_FLUSH post write
