Subject: Revert "sysupgrade: run only one instance at a time."
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=361c8b4ee4a20035d4c967d9d67db90d53e924a2;p=openwrt%2Fstaging%2Fadrian.git

Revert "sysupgrade: run only one instance at a time."

This reverts commit e96a9a9af82c00dcce606a84a7bb87a00411385d.

The change breaks sysupgrade through LuCI and two-stage sysupgrade on
NAND targets. There is also a mismatch of file paths in lock and unlock
operations.

This commit was apparently neither properly tested, nor reviewed, so
drop it for now.
