As explained during the 2018 LSF/MM session about increasing SCSI disk probing concurrency, the problems with the current probing approach are as follows: - The driver core is unaware of asynchronous SCSI LUN probing. wait_for_device_probe() waits for all asynchronous probes except asynchronous SCSI disk probes. - There is unnecessary serialization between sd_probe() and sd_remove(). This can lead to a deadlock. Hence this patch that modifies the sd driver such that it uses the driver core framework for asynchronous probing. The async domains and get_device()/put_device() pairs that became superfluous due to this change are removed. This patch does not affect the time needed for loading the scsi_debug kernel module with parameters delay=0 and max_luns=256. This patch depends on commit ef0ff683 ("driver core: Probe devices asynchronously instead of the driver") that went upstream in kernel version v5.1-rc1.

The variable len is not being inintialized and the uninitialized value is being returned. However, this return path is never reached because the default case in the switch statement returns -ENOSYS. Clean up the code by replacing the return -ENOSYS with a break for the default case and returning -ENOSYS at the end of the function. This allows len to be removed. Signed-off-by:

clang -Wuninitialized incorrectly sees a variable being used without initialization: drivers/scsi/lpfc/lpfc_nvme.c:2102:37: error: variable 'localport' is uninitialized when used here [-Werror,-Wuninitialized] lport = (struct lpfc_nvme_lport *)localport->private; ^~~~~~~~~ drivers/scsi/lpfc/lpfc_nvme.c:2059:38: note: initialize the variable 'localport' to silence this warning struct nvme_fc_local_port *localport; ^ = NULL 1 error generated. This is clearly in dead code, as the condition leading up to it is always false when CONFIG_NVME_FC is disabled, and the variable is always initialized when nvme_fc_register_localport() got called successfully. Change the preprocessor conditional to the equivalent C construct, which makes the code more readable and gets rid of the warning. Signed-off-by:James Smart <james.smart@broadcom.com> Signed-off-by:

Change snprintf to scnprintf. There are generally two cases where using snprintf causes problems. 1) Uses of size += snprintf(buf, SIZE - size, fmt, ...) In this case, if snprintf would have written more characters than what the buffer size (SIZE) is, then size will end up larger than SIZE. In later uses of snprintf, SIZE - size will result in a negative number, leading to problems. Note that size might already be too large by using size = snprintf before the code reaches a case of size += snprintf. 2) If size is ultimately used as a length parameter for a copy back to user space, then it will potentially allow for a buffer overflow and information disclosure when size is greater than SIZE. When the size is used to index the buffer directly, we can have memory corruption. This also means when size = snprintf... is used, it may also cause problems since size may become large. Copying to userspace is mitigated by the HARDENED_USERCOPY kernel configuration. The solution to these issues is to use scnprintf which returns the number of characters actually written to the buffer, so the size variable will never exceed SIZE. Signed-off-by:

You can't declare a function inline in a header if it doesn't have a body available to the compiler. So realistically you either don't declare it inline or you make it a static inline in the header. I think the latter applies in this case, so this should be the fix Signed-off-by:
