From d0a5b995a308347fdb1bb0412df32acd0312523b Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 29 Sep 2016 17:48:39 +0200 Subject: vfs: Add IOP_XATTR inode operations flag The IOP_XATTR inode operations flag in inode->i_opflags indicates that the inode has xattr support. The flag is automatically set by new_inode() on filesystems with xattr support (where sb->s_xattr is defined), and cleared otherwise. Filesystems can explicitly clear it for inodes that should not have xattr support.
