From: Andrii Staikov <andrii.staikov@intel.com> stable inclusion from stable-v6.6.2 commit d20700da63969ceef46f9fa0d56218a6440ceeb4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 5ca636d927a106780451d957734f02589b972e2b ] Instead of freeing memory of a single VSI, make sure the memory for all VSIs is cleared before releasing VSIs. Add releasing of their resources in a loop with the iteration number equal to the number of allocated VSIs.
