Subject: [PATCH 1/3] coredump: use MEMBER_{OFFSET, SIZE} instead of
|
|
|
f17523 |
GCORE_{OFFSET, SIZE}
|
|
|
f17523 |
|
|
|
f17523 |
fill_auxv_note() and compat_fill_auxv_note() is called just once each
|
|
|
f17523 |
time gcore command is invoked because each process has just one
|
|
|
f17523 |
NT_AUXV. This means using MEMBER_{OFFSET, SIZE} is enough; using
|
|
|
f17523 |
GCORE_{OFFSET, SIZE} is overkill.
