Subject: Use kernel slab for vn_cache and vn_file_cache
X-Git-Tag: spl-0.7.0-rc4~7
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=97048200f888afc0b1387bff75049cf37e9715bd;p=spl

Use kernel slab for vn_cache and vn_file_cache

Resolve a false positive in the kmemleak checker by shifting to the
kernel slab.  It shows up because vn_file_cache is using KMC_KMEM
which is directly allocated using __get_free_pages, which is not
automatically tracked by kmemleak.
