NAME
i2o_dma_realloc - Realloc DMA memory
SYNOPSIS
int i2o_dma_realloc(struct device * dev, struct i2o_dma * addr,
size_t len, gfp_t gfp_mask);
ARGUMENTS
- dev
- struct device pointer to the PCI device of the I2O controller
- addr
- pointer to a i2o_dma struct DMA buffer
- len
- new length of memory
- gfp_mask
- GFP mask
DESCRIPTION
If there was something allocated in the addr, free it first. If len > 0
than try to allocate it and write the addresses back to the addr
structure. If len == 0 set the virtual address to NULL.
Returns the 0 on success or negative error code on failure.
