This necessitates a large number of driver changes because the previous guarantee that if a driver specified SG_ALL as the size of its scatter list, it would get a non-chained list and didn't need to bother with scatterlist iterators is now broken and every driver *must* use scatterlist iterators. This was broken out as a separate topic because we need to convert all the drivers before pulling the trigger and unconverted drivers kept being found, necessitating a rebase" * tag 'scsi-sg' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (21 commits) scsi: core: don't preallocate small SGL in case of NO_SG_CHAIN scsi: lib/sg_pool.c: clear 'first_chunk' in case of no preallocation scsi: core: avoid preallocating big SGL for data scsi: core: avoid preallocating big SGL for protection information scsi: lib/sg_pool.c: improve APIs for allocating sg pool scsi: esp: use sg helper to iterate over scatterlist scsi: NCR5380: use sg helper to iterate over scatterlist scsi: wd33c93: use sg helper to iterate over scatterlist scsi: ppa: use sg helper to iterate over scatterlist scsi: pcmcia: nsp_cs: use sg helper to iterate over scatterlist scsi: imm: use sg helper to iterate over scatterlist scsi: aha152x: use sg helper to iterate over scatterlist scsi: s390: zfcp_fc: use sg helper to iterate over scatterlist scsi: staging: unisys: visorhba: use sg helper to iterate over scatterlist scsi: usb: image: microtek: use sg helper to iterate over scatterlist scsi: pmcraid: use sg helper to iterate over scatterlist scsi: ipr: use sg helper to iterate over scatterlist scsi: mvumi: use sg helper to iterate over scatterlist scsi: lpfc: use sg helper to iterate over scatterlist scsi: advansys: use sg helper to iterate over scatterlist ...
| * scsi: mvumi: use sg helper to iterate over scatterlistMing Lei2019-06-201-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the legacy I/O path, scsi-mq preallocates a large array to hold the scatterlist for each request. This static allocation can consume substantial amounts of memory on modern controllers which support a large number of concurrently outstanding requests. To facilitate a switch to a smaller static allocation combined with a dynamic allocation for requests that need it, we need to make sure all SCSI drivers handle chained scatterlists correctly. Convert remaining drivers that directly dereference the scatterlist array to using the iterator functions.
