A patch that was added to 4.0-rc1 in the last minute caused a build break in the NVMe driver unless integrity support is also enabled:drivers/block/nvme-core.c: In function 'nvme_dif_remap': drivers/block/nvme-core.c:523:24: error: dereferencing pointer to incomplete type pmap = kmap_atomic(bip->bip_vec->bv_page) + bip->bip_vec->bv_offset; ^ drivers/block/nvme-core.c:523:49: error: dereferencing pointer to incomplete type pmap = kmap_atomic(bip->bip_vec->bv_page) + bip->bip_vec->bv_offset; ^ This changes the Kconfig entry for NVMe to depend on that support, to avoid the build error. Using 'select' would work as well, but might have unintended side-effects when users do not actually want the integerity support.
Thanks for the catch. We do want users to be able to use this with and without blk-integrity, so I'll send a patch using conditional functions between appropriate ifdef's like how scsi and block handle this. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
