Subject: can't cleanup /proc/swaps without rebooting ?

hi All,

Please could you cc me because I'm not subscribed.


is there a way, other than rebooting, to clean up /proc/swaps ?

I'm in this situation (due to testing errors),
# cat /proc/swaps
Filename Type Size Used Priority
/dev/sdc1 partition 2040064 0 -1
/tmp/swaH4mvTI/swapfilenext\040(deleted) file 48960 0 -31
/tmp/swa5TlBva/swapfilenext\040(deleted) file 49088 0 -118
#
# swapon -s
Filename Type Size Used Priority
/dev/sdc1 partition 2040064 0 -1
/tmp/swaH4mvTI/swapfilenext\040(deleted) file 48960 0 -31
/tmp/swa5TlBva/swapfilenext\040(deleted) file 49088 0 -118
#

many thanks,

"swapoff /dev/sdc1" or "swapoff /tmp/swa5TlBva/swapfilenext". Don't
know if the latter works when the file is unlinked, just try.

Good question. Sorry, I don't see another way than rebooting.
Next time you're testing, best keep a link to those swapfiles.
Not an answer to be proud of, but it looks like a better answer
would need a whole new syscall (or perhaps some /proc trickery).
