[PATCH] ufs2 write: mount as rw
These series of patches add UFS2 write-support. UFS2 - is default file system
for recent versions of FreeBSD.
The main differences from UFS1 from write support point of view
are:
1)Not all inodes are allocated during formatation of disk.
2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they
are 32bit).
So patch series consist of
1)make possible mount UFS2 in read-write mode
2)code to write ufs2 inodes and code to initialize inodes chunks.
3)work with 64bit meta-data
I made simple testing like create/deleting/writing/reading/truncating, also I
ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD
fsck do not find any errors in fs.
This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation:
remove note about bug(it fixed by reallocate blocks on the fly patch) and add
me in the list of people who want receive bug reports.
