[PATCH 2/2] Coccinelle: extend memdup_user rule with vmemdup_user()

Add vmemdup_user() transformations to the memdup_user.cocci rule. Commit 50fd2f298bef ("new primitive: vmemdup_user()") introduced vmemdup_user(). The function uses kvmalloc with GPF_USER flag. Signed-off-by: Denis Efremov --- scripts/coccinelle/api/memdup_user.cocci | 49 +++
