But\nfor \"oops\" the situation is more complex - the kernel may carry on\nrunning (possibly for ever).  So we\u0027d like to make the logged copy\nof the oops appear in the pstore filesystem - so that the user has\na handle to clear the entry from the persistent backing store (if\nwe don\u0027t, the store may fill with \"oops\" entries (that are also\nsafely stashed in /var/log/messages) leaving no space for real\nerrors.\n\nCurrent code calls pstore_mkfile() immediately. But this may\nnot be safe. The oops could have happened with arbitrary locks\nheld, or in interrupt or NMI context. So allocating memory and\ncalling into generic filesystem code seems unwise.\n\nThis patch defers making the entry appear. At the time\nof the oops, we merely set a flag \"pstore_new_entry\" noting that\na new entry has been added. A periodic timer checks once a minute\nto see if the flag is set - if so, it schedules a work queue to\nrescan the backing store and make all new entries appear in the\npstore filesystem.\n\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n"
