Hi Cyril, Alejandro,

also, its nice that only /sys/fs/smackfs and /sys/kernel/cgroup/ are not
covered (both are subsystems are at least somehow covered in LTP).
=> very good test coverage.

$ for i in $(grep -h '.I /sys' ../man-pages.git/man/man5/sysfs.5 | cut -d  ' ' -f2); do git grep -q $i || echo "$i is missing"; done
/sys/fs/smackfs is missing
/sys/kernel/cgroup/ is missing

@Alejandro FYI man/man5/sysfs.5 (or other man pages) could be updated, few
/sys/ directories are missing:

man/man5/sysfs.5 (I haven't found more specific man page)
/sys/class/ata_device
/sys/class/bdi
/sys/class/hwmon
/sys/class/leds
/sys/class/thermal
/sys/class/wakeup
/sys/devices/system/cpu/vulnerabilities

man/man4/loop.4
/sys/block/loop

man/man4/rtc.4
/sys/class/rtc

I'm not sure if these should be documented in man page:

/sys/devices/system
/sys/devices/system/clockevents
/sys/devices/system/clocksource
/sys/kernel/mm/ksm
/sys/kernel/mm/swap

Kind regards,
Petr

This message seems to be in reply to another one, but that other one
isn't quoted, and I can't find it in either mailing list archives.

Sure!  Feel free to send patches documenting those, if you know their
interfaces.  (If you start working on that, please let me know, just to
avoid doing stuff that might cause conflicts with your work.)


Have a lovely day!
