XFS for Linux Release 1.0.1 New Features

XFS for Linux Release 1.0.1 differs from Release 1.0 in the following areas:

• Some of the ACL library's functions have been changed to comply with the POSIX ACL (P1003.1e) withdrawn standard. These changes make it simpler for the Samba code to work with XFS. A bug was also fixed for chacl -d.

  • unused code & gratuitous prototypes were removed
  • unused debug checking was removed
  • compiler warnings were fixed

• Kernel packaged in 2.4.3 RPM based on updated RPM from Redhat

• Unmount of dirty filesystem speeded up

• inode fields pared down, shrinking inode by 60-70 bytes

• Permission checking on full file fixed

• Optimizations based on kernel profiling made

• Changes made to help with compiler independence (but egcs-2.91.66 is still preferred & tested at SGI)

• ATIME not updated for extended attribute or ACL changes

• Default BIOSIZE changed to 4k to fix some db-related size issues

• "Best" AG size changed from 1GB to 4GB when the filesystem exceeds 64GB
