New Revision: 322030
URL: https://svnweb.freebsd.org/changeset/base/322030

Log:
  Bump the maximum file name length in pseudofs filesystems to 48.
  
  The previous limit of 24 was somewhat restrictive, and with this change
  ceil(log2(sizeof(struct pfs_node))) is the same as before in both the ILP32
  and LP64 models, so the malloc zone used for allocations of struct pfs_node
  is the same as before.
