From: Andreas Gruenbacher Date: Sun, 4 Oct 2015 17:18:54 +0000 (+0200) Subject: f2fs: xattr simplifications X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=29608d208b3619b3b508a6871622db789611d8a3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git f2fs: xattr simplifications Now that the xattr handler is passed to the xattr handler operations, we have access to the attribute name prefix, so simplify f2fs_xattr_generic_list. Also, f2fs_xattr_advise_list is only ever called for f2fs_xattr_advise_handler; there is no need to double check for that.
