**调用者**
名称	描述
__blkdev_issue_discard
__blkdev_issue_write_same	__blkdev_issue_write_same - generate number of bios with same page@bdev: target blockdev@sector: start sector@nr_sects: number of sectors to write@gfp_mask: memory allocation flags (for bio_alloc)@page: page containing data to write@biop: pointer to
__blkdev_issue_zeroout	__blkdev_issue_zeroout - generate number of zero filed write bios@bdev: blockdev to issue@sector: start sector@nr_sects: number of sectors to write@gfp_mask: memory allocation flags (for bio_alloc)@biop: pointer to anchor bio@flags: controls
blkdev_issue_zeroout	lkdev_issue_zeroout - zero-fill a block range@bdev: blockdev to write@sector: start sector@nr_sects: number of sectors to write@gfp_mask: memory allocation flags (for bio_alloc)@flags: controls detailed behavior Description:* Zero-fill a block
blkpg_ioctl
blkdev_ioctl	always keep this in sync with compat_blkdev_ioctl()
atari_partition
parse_extended	Create devices for each logical partition in an extended partition.* The logical partitions form a linked list, with each entry being* a partition table with two entries. The first entry* is the real data partition (with a start relative to the partition
msdos_partition
ibm_partition	This is the main function, called by check.c
last_lba	last_lba(): return number of last logical block of device@bdev: block device Description: Returns last LBA value on success, 0 on error.* This is stored (by sd and ide-geometry) in* the part[0] entry for this disk, and is the number of
read_lba	ad_lba(): Read bytes from disk, starting at given LBA@state: disk parsed partitions@lba: the Logical Block Address of the partition table@buffer: destination buffer@count: bytes to read* Description: Reads @count bytes from @state->bdev into @buffer.
alloc_read_gpt_header	alloc_read_gpt_header(): Allocates GPT header, reads into it from disk@state: disk parsed partitions@lba: the Logical Block Address of the partition table* Description: returns GPT header on success, NULL on error. Allocates
is_gpt_valid	s_gpt_valid() - tests one GPT header and PTEs for validity@state: disk parsed partitions@lba: logical block address of the GPT header to test@gpt: GPT header ptr, filled on return.@ptes: PTEs ptr, filled on return.
efi_partition	_partition(struct parsed_partitions state)@state: disk parsed partitions* Description: called from check.c, if the disk contains GPT* partitions, sets up partition entries in the kernel.* If the first block on the disk is a legacy MBR,
compat_blkdev_ioctl	Most of the generic ioctls are handled in the normal fallback path.This assumes the blkdev's low level compat_ioctl always returnsENOIOCTLCMD for unknown ioctls.

blkdev_fallocate
do_blockdev_direct_IO	This is a library function for use by filesystem drivers
