* Fix error check.Kirk McKusick2013-04-231-1/+1

* The purpose of this change to the FFS layout policy is to reduce theKirk McKusick2013-03-222-8/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | running time for a full fsck. It also reduces the random access time for large files and speeds the traversal time for directory tree walks. The key idea is to reserve a small area in each cylinder group immediately following the inode blocks for the use of metadata, specifically indirect blocks and directory contents. The new policy is to preferentially place metadata in the metadata area and everything else in the blocks that follow the metadata area. The size of this area can be set when creating a filesystem using newfs(8) or changed in an existing filesystem using tunefs(8). Both utilities use the `-k held-for-metadata-blocks' option to specify the amount of space to be held for metadata blocks in each cylinder group. By default, newfs(8) sets this area to half of minfree (typically 4% of the data area). This work was inspired by a paper presented at Usenix's FAST '13: www.usenix.org/conference/fast13/ffsck-fast-file-system-checker Details of this implementation appears in the April 2013 of ;login: www.usenix.org/publications/login/april-2013-volume-38-number-2. A copy of the April 2013 ;login: paper can also be downloaded from: www.mckusick.com/publications/faster_fsck.pdf.

The storage may not actually be contiguous but is at least within one cg. - When disabling SUJ leave SU enabled and report this to the user.

* Create a new 32-bit fs_flags word in the superblock. Add code to moveKirk McKusick2002-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | the old 8-bit fs_old_flags to the new location the first time that the filesystem is mounted by a new kernel. One of the unused flags in fs_old_flags is used to indicate that the flags have been moved. Leave the fs_old_flags word intact so that it will work properly if used on an old kernel. Change the fs_sblockloc superblock location field to be in units of bytes instead of in units of filesystem fragments. The old units did not work properly when the fragment size exceeeded the superblock size (8192). Update old fs_sblockloc values at the same time that the flags are moved.
