Subject: f2fs crypto: avoid f2fs_inherit_context for symlink
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e992e238ff93920da65f5aa83d3f3e257530ce8b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

f2fs crypto: avoid f2fs_inherit_context for symlink

This patch fixes to call f2fs_inherit_context twice for newly created symlink.
The original one is called by f2fs_add_link(), which invokes f2fs_setxattr.
If the second one is called again, f2fs_setxattr is triggered again with same
encryption index.
