+ ELF core dump files describe each memory mapping of the crashed
+ process, and can contain or omit the memory contents of each one.
+ The contents of an unmodified text mapping are omitted by default.
+
+ For an unmodified text mapping of an ELF object, including just
+ the first page of the file in a core dump makes it possible to
+ identify the build ID bits in the file, without paying the i/o
+ cost and disk space to dump all the text. However, versions of
+ GDB before 6.7 are confused by ELF core dump files in this format.
+
+ The core dump behavior can be controlled per process using
+ the /proc/PID/coredump_filter pseudo-file; this setting is
+ inherited. See Documentation/filesystems/proc.txt for details.
+
+ This config option changes the default setting of coredump_filter
+ seen at boot time. If unsure, say N.
