Commit Message

Mingjin Ye March 14, 2024, 9:36 a.m. UTC 
  The asan tool detected a memory leak in the vdev driver
alloc_devargs. The previous commit was that when inserting
a vdev device, the primary process alloc devargs and the
secondary process looks for devargs. This causes the
device to not be created if the secondary process does
not initialise the vdev device. And, this is not the
root cause.

Therefore the following commit was reverted accordingly.

Fixes: 6666628362c9 ("bus/vdev: fix devargs in secondary process")

After restoring this commit, the memory leak still exists.
A new patch has since fixed this issue.
