EDAC\/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation<\/p>\n
The poll_msec sysfs store file uses simple_strtoul() which accepts an unsigned
\nlong, but the target field (poll_msec) is unsigned int. On 64-bit systems,
\na value > UINT_MAX is silently truncated when stored.<\/p>\n
Fix the mismatch by using kstrtouint() instead. This rejects values larger
\nthan UINT_MAX at parse time, making truncation impossible. Also add a check
\nfor value < 1 to reject the 0-delay case, which would cause the poll work to
\nspin without delay and consume 100% CPU.<\/p>\n","protected":false},"excerpt":{"rendered":"
