From de93653fe31fc9439971296842dcd0280f8ab5f4 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 12 Aug 2013 21:08:03 +0900 Subject: f2fs: reserve the xattr space dynamically This patch enables the number of direct pointers inside on-disk inode block to be changed dynamically according to the size of inline xattr space. The number of direct pointers, ADDRS_PER_INODE, can be changed only if the file has inline xattr flag. The number of direct pointers that will be used by inline xattrs is defined as F2FS_INLINE_XATTR_ADDRS. Current patch assigns F2FS_INLINE_XATTR_ADDRS to 0 temporarily.
