[PATCH 0/2] scsi: lpfc: Cleanup some bitmap handling.

[Christophe JAILLET]

The 1st patch of this serie uses bitmap_zalloc() to simplify code.
The 2nd patch makes sure that the whole bitmap is cleared, should it need more
than 1 long.

However, this 'fcf_rr_bmask' is small (LPFC_SLI4_FCF_TBL_INDX_MAX = 32 bits), so
another option could be to use DECLARE_BITMAP instead of dynamic allocation.

This would simplify code (no more allocation and associated error handling) and
be slighly more efficient (1 less indirection when accessing the bitmap).
In the case the 2nd patch could also be removed (using bitmap_zero() would still
be cleaner (IMHO), but the actual memset+sizeof would work as expected)

Let me know if I should send a v2 with this other approach.
