Subject[PATCH 2/4] evm: reset status in evm_inode_post_setattr()
Date
This patch adds a call to evm_reset_status() in evm_inode_post_setattr(),
before security.evm is updated. The same is done in the other
evm_inode_post_* functions.

Fixes: 523b74b16bcbb ("evm: reset EVM status when file attributes change")
