This patch is going into testing at one of our large customers, and I want to make sure that we don't accidentally get a conflicting INCOMPAT flag assignment. #define EXT4_FEATURE_INCOMPAT_EA_INODE 0x0400 #define EXT4_FEATURE_INCOMPAT_DIRDATA 0x1000 #define EXT4_EA_INODE_FL 0x00200000 /* Inode used for large EA */ Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.
