After debian bug #192277, debian/rules started making a symlink

[ Changed by tytso to remove the explicit -s option; this will default
to creating a hard link by default, which slightly faster. If
people want to use symlinks for all links during the install

The reason for this change is that some file systems, like AFS,
don't support symlinks, and AFS users complain when they can't build

unconditionally without a way of switching things back and forth,
and it's easier if we just make all links made during the install

resize2fs: do not clear resize inode for 0 resvd blocks
I ran into odd behavior where mkfs.ext4 of a 16T filesystem would
create a resize inode with 0 reserved blocks, and mark the resize_inode
feature.
A subsequent slight downward resize of the filesystem would remove
the resize inode, making any further offline resizing impossible.
This is especially odd in light of the fact that a large downward
resize (say, to 8T) will actually add blocks to the resize inode -
so a small resize removes it, a large resize expands it ...
commit
8ade268cf2fde8629b51bfd1c044a83db88234cd had added this:
If the filesystem is grown to the point where the resize_inode is no
longer needed, clean it up properly so e2fsck doesn't have to.
but, it seems e2fsck does not care about this situation, either.
So, simply leave the resize_inode intact in this case, and everything
seems to be happy.

e2fsck: Add the ability to force a problem to not be fixed
The boolean options "force_no" in the problems stanza of e2fsck.conf
allows a particular problem code be treated as if the user will answer
"no" to the question of whether a particular problem should be fixed
--- even if e2fsck is run with the -y option.
As an example use case, suppose a distribution had widely deployed a
version of the kernel where under some circumstances, the EOFBLOCKS_FL
flag would be left set even though it should not be left set, and a
customer had a workload which exercised the fencepost error all the
time, resulting in many large number of inodes that had EOFBLOCKS_FL
set erroneously. Enough, in fact, the e2fsck runs were taking too
long. (There was such a bug in the kernel, which was fixed by commit
58590b06d in 2.6.36).
Leaving EOFBLOCKS_FL set when it should not be isn't a huge deal, and
is certainly than having high availability timeout alerts going off
left and right. So in this case, the best fix might be to put the
following in /etc/e2fsck.conf:
[problems]
0x010060 = { # PR_1_EOFBLOCKS_FL_SET
force_no = true
no_ok = true

Reserve the EXT4_FEATURE_INCOMPAT_DIRDATA feature flag
Reserve the EXT4_FEATURE_INCOMPAT_DIRDATA feature flag for adding
extra file data in ext2_dir_entry_2 entries.
This changes the on-disk layout in the following way.
Firstly, the ext2_dir_entry_2 file_type field now has a mask: that
limits the "filetype" information to the low 4 bits of this field.
Since these values are sequentially assigned, this allows for up to 7
more filetypes to be assigned. When reading the "filetype" field, the
high 4 bits should be masked off when converting to DT_* filetypes for
userspace.
The high 4 bits of "filetype" are used as a bitmask to register up to
4 different "extended" directory entry fields. Extended data fields
are packed without alignment into the directory entry after the "name"
field in order of increasing bitmask value, for each field where bit
is set. In order to avoid the need to "understand" each of the
extended fields, the first byte of each extended data field holds the
size of that data field (including the size itself), so they can be
skipped if not understood. For fields that change the semantics of
the filesystem it is expected that a separate ROCOMPAT or INCOMPAT
field is registered.
There is a single dirent data type defined currently, for Lustre:
which holds a 128-bit file identifier. It is expected that if there
are 64-bit inode values that this will be assigned the 0x20 value.
Should a need ever arise to use all 4 of the extended dirent data
fields, it would be possible to keep the last bit (0x80) for use as a
multiplexor that stores a 1-byte aggregate data size, then a series of
"<u8_size><u8_type><data>" records in the last extended data record.
It is not expected that this will actually be needed in the lifetime
of ext4.

Reserve the EXT4_INCOMPAT_EA_INODE feature flag
Reserve the EXT4_INCOMPAT_EA_INODE feature flag for use with
large extended attributes that are stored in a separate inode.
This changes the on-disk format in several ways:
First, replace the e_value_block field with e_value_inum, so that
an xattr entry can reference an external inode. This field is
currently unused, as all of the entries live in the same block.
struct ext2_ext_attr_entry {
__u8 e_name_len; /* length of name */
__u8 e_name_index; /* attribute name index */
__le16 e_value_offs; /* offset in disk block of value */
> __le32 e_value_inum; /* inode in which the value is stored */
__le32 e_value_size; /* size of attribute value */
__le32 e_hash; /* hash value of name and value */
char e_name[0]; /* attribute name */
}
Second, add a flag to the inode that indicates it is using a large
(external) extended attribute. This is needed so that when unlinking
an inode the xattrs will be scanned to unlink the xattr inodes
referenced by the main inode.
Third, for inodes that have a number of xattrs that are larger than
a single block, but not large enough to justify an external inode
(less than 64kB total xattr size, due to e_value_offs limitation)
the ext2_ext_attr_header->h_blocks field can grow beyond a single
block to represent a contiguous allocation of blocks for the xattr.
