NAME¶
bio_alloc_bioset - allocate a bio for I/OSYNOPSIS¶
struct
bio * bio_alloc_bioset(gfp_t gfp_mask,
int nr_iovecs,
struct bio_set * bs);
ARGUMENTS¶
gfp_maskthe GFP_ mask given to the slab
allocator
nr_iovecs
number of iovecs to pre-allocate
bs
the bio_set to allocate from.
DESCRIPTION¶
bio_alloc_bioset will try its own mempool to satisfy the allocation. If __GFP_WAIT is set then we will block on the internal pool waiting for a struct bio to become free. Note that the caller must set ->bi_destructor on successful return of a bio, to do the appropriate freeing of the bio once the reference count drops to zero.COPYRIGHT¶
