Subject: CacheFiles: Update IMA counters when using dentry_open
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3350b2acdd39d23db52710045536b943fe38a35c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

CacheFiles: Update IMA counters when using dentry_open

When IMA is active, using dentry_open without updating the
IMA counters will result in free/open imbalance errors when
fput is eventually called.
