Bug ID: 26811
Summary: adapt to kernel 5.10 set_fs() removal
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: me at serhei dot io
Target Milestone: ---
We use set_fs() across a number of places in the runtime along with the related
get_fs,USER_DS,KERNEL_DS. Go through and excise these uses when STAPCONF_SET_FS
is not active, in favour of other mechanism(s(?)).

There are still some problems with kernel faults (e.g. systemtap.examples whythefail.stp) which didn't occur in testing on older kernels. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
