Subject: Please reserve INCOMPAT flags

Ted,
in addition to the data-in-dirent INCOMPAT flag Rahul sent the patches
for last week, I would like to ensure that we also have the INCOMPAT
flag for large EA-in-inode flag reserved.  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
