The nopout's reserved field was not being initialized to zero before being reused. Stale CDB values from previous SCSI cmds of the same BHS offset was the cause of the disconnection initiated by the Lefthand target. Signed-off-by:

After a reset, we should first wait for the board to become "not ready", and then wait for it to become "ready", instead of immediately waiting for it to become "ready", and do this waiting *after* restoring PCI config space registers. Also, only wait 10 secs for board to become "not ready" after a reset (it should quickly become not ready.) Signed-off-by:

Currently NetApp's VID/PID details in the INQUIRY response shows up as 'NETAPP' and 'LUN'. With upcoming scalable SAN ONTAP version on NetApp controllers, the PID entry alone is being modified to 'LUN C-Mode' (to distinguish current ONTAP LUNs from scalable ONTAP LUNs). 'LUN' would still suffice for matching 'LUN C-Mode' but best to explicitly add these new NetApp LUNs to the device list. Reported-by:

Initialize stpg_endio() 'err' to SCSI_DH_OK and only change it to SCSI_DH_IO accordingly. This allows the switching of target group state to be properly reported when no error has occurred. Signed-off-by:

submit_stpg() will always return failure so alua_activate() will report failure via dm-multipath callback function. Even though the stpg fired successfuly dm-multipath does not know and always fails to change the valid path. By returning SCSI_DH_OK we're now skipping alua_activate()'s call to activate_complete 'fn'. But this is fine because stpg_endio() will call it via h->callback_fn(). Signed-off-by:

Basic Code Cleanup: (1) _base_get_cb_idx and mpt2sas_base_free_smid were reorganized in similar fashion so the order of obtaining the cbx and smid are scsiio, hi_priority, and internal. (2) The hi_priority and internal request queue struct was made smaller by removing the scmd and chain_tracker, thus saving memory allocation. (3) For scsiio request, a new structure was created having the same elements from the former request tracker struct. Signed-off-by:

Now BUILD_BUG_ON() can handle optimizable constants, we don't need MAYBE_BUILD_BUG_ON any more. Signed-off-by:Rusty Russell <rusty@rustcorp.com.au>
-
Rusty Russell authored
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df45) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by:

Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace. This patch changes MODULE_VERSION() macro so that in case when we are compiling built-in module, version information is stored in a separate section. Kernel then uses this data to create 'version' sysfs attribute in the same fashion it creates attributes for module parameters. Signed-off-by:

commit 3f0d3d01 adds a check for PNP device id to the common tpm_tis_init() function, which in some cases (force=1) will be called without the device being a member of a pnp_dev. Oopsing and panics ensue. Move the test up to before the call to tpm_tis_init(), since it just modifies a global variable anyway. Signed-off-by:

If duration variable value is 0 at this point, it's because chip->vendor.duration wasn't filled by tpm_get_timeouts() yet. This patch sets then the lowest timeout just to give enough time for tpm_get_timeouts() to further succeed. This fix avoids long boot times in case another entity attempts to send commands to the TPM when the TPM isn't accessible. Signed-off-by:
