Subject: ext4: Rename ext4dev to ext4 | 
						|
X-Git-Tag: v2.6.28-rc1~709^2 |

ext4: Rename ext4dev to ext4 | 
						|
 | 
						|
The ext4 filesystem is getting stable enough that it's time to drop | 
						|
the "dev" prefix.  Also remove the requirement for the TEST_FILESYS | 
						|
flag. |

-	  Ext4dev is a predecessor filesystem of the next generation | 
						|
-	  extended fs ext4, based on ext3 filesystem code. It will be | 
						|
-	  renamed ext4 fs later, once ext4dev is mature and stabilized. | 
						|
+	  This is the next generation of the ext3 filesystem. | 
						|
  | 
						|
 	  Unlike the change from ext2 filesystem to ext3 filesystem, | 
						|
-	  the on-disk format of ext4dev is not the same as ext3 any more: | 
						|
-	  it is based on extent maps and it supports 48-bit physical block | 
						|
-	  numbers. These combined on-disk format changes will allow | 
						|
-	  ext4dev/ext4 to handle more than 16 TB filesystem volumes -- | 
						|
-	  a hard limit that ext3 cannot overcome without changing the | 
						|
-	  on-disk format. | 
						|
- | 
						|
-	  Other than extent maps and 48-bit block numbers, ext4dev also is | 
						|
-	  likely to have other new features such as persistent preallocation, | 
						|
-	  high resolution time stamps, and larger file support etc.  These | 
						|
-	  features will be added to ext4dev gradually. | 
						|
+	  the on-disk format of ext4 is not forwards compatible with | 
						|
+	  ext3; it is based on extent maps and it supports 48-bit | 
						|
+	  physical block numbers.  The ext4 filesystem also supports delayed | 
						|
+	  allocation, persistent preallocation, high resolution time stamps, | 
						|
+	  and a number of other features to improve performance and speed | 
						|
+	  up fsck time.  For more information, please see the web pages at | 
						|
+	  http://ext4.wiki.kernel.org. | 
						|
+ | 
						|
+	  The ext4 filesystem will support mounting an ext3 | 
						|
+	  filesystem; while there will be some performance gains from | 
						|
+	  the delayed allocation and inode table readahead, the best | 
						|
+	  performance gains will require enabling ext4 features in the | 
						|
+	  filesystem, or formating a new filesystem as an ext4 | 
						|
+	  filesystem initially. |
