With these patches, msgmni has a registered notification\nroutine that recomputes msgmni value upon memory add/remove or ipc\nnamespace creation/ removal.\n\nWhen msgmni is changed from user space (i.e. value written to the proc\nfile), that notification routine is unregistered, and the way to make it\nregistered back is to write a negative value into the proc file. This is\nthe \"magical positive-versus-negative number trick\".\n\nTo fix this, a new proc file is introduced: /proc/sys/kernel/auto_msgmni.\nThis file acts as ON/OFF for msgmni automatic recomputing.\n\nWith this patch, the process is the following:\n1) kernel boots in \"automatic recomputing mode\"\n /proc/sys/kernel/msgmni contains the value that has been computed (depends\n on lowmem)\n /proc/sys/kernel/automatic_msgmni contains \"1\"\n\n2) echo \u003cval\u003e \u003e /proc/sys/kernel/msgmni\n . sets msg_ctlmni to \u003cval\u003e\n . de-activates automatic recomputing (i.e. if, say, some memory is added\n msgmni won\u0027t be recomputed anymore)\n . /proc/sys/kernel/automatic_msgmni now contains \"0\"\n\n3) echo \"0\" \u003e /proc/sys/kernel/automatic_msgmni\n . de-activates msgmni automatic recomputing\n this has the same effect as 2) except that msg_ctlmni\u0027s value stays\n blocked at its current value)\n\n3) echo \"1\" \u003e /proc/sys/kernel/automatic_msgmni\n . recomputes msgmni\u0027s value based on the current available memory size\n and number of ipc namespaces\n . re-activates automatic recomputing for

Since it is a pointer copy, the new spi_device\nremains dependent on the spi_board_info structure after the new spi_device\nis registered (no other fields in spi_device directly depend on the\nspi_board_info structure; all of the other data is copied).\n\nThis causes a problem when dynamically propulating the list of attached\nSPI devices.
