badblocks

Name:adblocks_show() - sysfs access to bad-blocks list*@bb: the badblocks structure that holds all badblock information*@page: buffer received from sysfs*@unack: weather to show unacknowledged badblocks* Return:* Length of returned data

Proto:ssize_t badblocks_show(struct badblocks *bb, char *page, int unack)

Type:ssize_t

Parameter:

Type	Parameter	Name
struct badblocks *	bb
char *	page
int	unack

p = badblock list

474

If shift from sectors to block size * a -ve shift means badblocks are * disabled. < 0 Then Return 0

477

retry :

478

seq = Read side functions for starting and finalizing a read side section.

480

len = 0

481

i = 0

483

When len < PAGE_SIZE && i < count of bad blocks cycle

484

s = BB_OFFSET(p[i])

485

length = BB_LEN(p[i])

486

ack = BB_ACK(p[i])

488

i++

If unack && ack Then Continue

493

len += snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@

497

If unack && len == 0 Then there probably are unacknowledged * bad blocks. This is only cleared * when a read discovers none = 0

500

If read_seqretry( & lock, seq) Then Go to retry

503

Return len
