When the M_SWAP column is enabled, it shows swap usage of processes. However, without cap_sys_ptrace, htop cannot show the swap usage of processes owned by other users. The SWAP column will simply show 0 bytes for other users' processes. If the cap_sys_ptrace file capability is added to the htop binary, then any user can see the amount of swap used by all processes. The ebuild for htop ought to add that file capability to the binary so that the M_SWAP column will work as intended. Gentoo users that wish to not add that file capability, could do so by disabling the filecaps USE flag on the package. Reproducible: Always Steps to Reproduce: 1. As root, run some memory heavy processes so that swap is utilized by them. Virtual machines (e.g. qemu) are a good candidate. 2. As an unprivileged user, run htop and enable the M_SWAP column 3. Note that the SWAP column will show 0 for the root processes that are using SWAP 4. As root, run htop and enable the M_SWAP column 5. Not that now the SWAP column will show actual swap usage for root (and all other) processes Actual Results: The SWAP column doesn't show correct swap usage for all processes. Expected Results: The SWAP column should show correct swap usage for all processes.

Instead of being put in the non-live ebuilds it was reversed in 20d5319d31378762c32b0b2344e24f37ffbaccd2. Was that a mistake or do we not want it? I we do not want it then can this bug be closed?

Pretty sure that was accidental. From looking at commit history, I suspect I had the commit in a branch and rebased it and it got lost then.
If I were to add it again which version should I target? Latest for sure but should I also add it to latest stable? If so, should I destabilize it? Also, should this bug be confirmed?

No. Just in a new revision and live. > If so, should I destabilize it? > > Also, should this bug be confirmed? I guess. We don't really do UNCO/CONF in Gentoo.
