PR31373: Deal with the removal of strlcpy() from linux 6.8
|
|
|
|
The Linux 6.8 kernels removed strlcpy() with git commit d26270061a in
|
|
January 2024. All the kernel's strlcpy() uses were converted to
|
|
strscpy(). Systemtap needed to do the same. This is implemented in
|
|
systemtap with a strlcpy macro in the runtime that translates the
|
|
strscpy() return value into the equivalent strlcpy() value.
