7 `coredump` is a feature which dumps a process's memory space when the process terminates
9 `coredump` dumps the memory to the file named `core`, but this behavior can be changed by writing a
10 different file name to `/proc/sys/kernel/core_pattern`. Furthermore, `coredump` can be piped to a
21 reads zero. But when the thread is dead (e.g. during a coredump), this field should have valid
24 However, this was broken in the past and `kstkesp` was zero even during coredump:
35 * commit 92307383082d ("coredump: Don't perform any cleanups before dumping core") broke it again
42 This test detects problem with reading `kstkesp` during coredump by doing the following:
