Name:__badblocks_init
Proto:static int __badblocks_init(struct device *dev, struct badblocks *bb, int enable)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct device * | dev | |
struct badblocks * | bb | |
int | enable |
548 | count of bad blocks = 0 |
549 | If enable Then shift from sectors to block size * a -ve shift means badblocks are * disabled. = 0 |
553 | If dev Then badblock list = devm_kzalloc(dev, PAGE_SIZE, GFP_KERNEL) |
555 | Else badblock list = kzalloc - allocate memory. The memory is set to zero.*@size: how many bytes of memory are required.*@flags: the type of memory to allocate (see kmalloc). |
557 | If Not badblock list Then |
559 | Return -ENOMEM |
561 | seqlock_init( & lock) |
563 | Return 0 |
Name | Describe |
