This solves a number of performance issues with random writes to medium sized files using large block sizes, as occurs with DBM files. This commit was manufactured by cvs2svn to create branch 'RELENG_4'. 2000-03-13T04:59:44Z cvs2svn cvs2svn@FreeBSD.org 2000-03-13T04:59:44Z urn:sha1:842f30848780866cb822fe01c4d3d4576718ddb3 Don't forget to check for unsupported features when updating.

Centralized the magic number and compatibility checking. Dropped support for ancient (pre-0.2b) filesystems, as in the Linux version. Our "support" consisted of printing more details in the error message before failing at mount time. Merged changes in ext2_fs.h between Linux 1.2.2 and Linux 2.3.35.

These changes are not used yet, except for a spelling change which affects ext2_cnv.c
