ll_rw_block
LL_RW_BLOCK(9) The Linux VFS LL_RW_BLOCK(9)
NAME
ll_rw_block - level access to block devices (DEPRECATED)
SYNOPSIS
void ll_rw_block(int rw, int nr, struct buffer_head * bhs[]);
ARGUMENTS
rw
whether to READ or WRITE or SWRITE or maybe READA (readahead)
nr
number of struct buffer_heads in the array
bhs[]
array of pointers to struct buffer_head
DESCRIPTION
ll_rw_block takes an array of pointers to struct buffer_heads, and requests an I/O operation on them, either a READ or a WRITE. The third
SWRITE is like WRITE only we make sure that the *current* data in buffers are sent to disk. The fourth READA option is described in the
documentation for generic_make_request which ll_rw_block calls.
This function drops any buffer that it cannot get a lock on (with the BH_Lock state bit) unless SWRITE is required, any buffer that appears
to be clean when doing a write request, and any buffer that appears to be up-to-date when doing read request. Further it marks as clean
buffers that are processed for writing (the buffer cache won't assume that they are actually clean until the buffer gets unlocked).
ll_rw_block sets b_end_io to simple completion handler that marks the buffer up-to-date (if approriate), unlocks the buffer and wakes any
waiters.
All of the buffers must be for the same device, and must also be a multiple of the current approved size for the device.
