* dir.c (diskfs_get_directs): Initialize `err' to shut gcc up. 1999-09-07 Thomas Bushnell, BSG <tb@mit.edu> * dir.c (diskfs_lookup_hard): Pass additional parameter to diskfs_get_filemap. (diskfs_dirempty): Likewise. * sizes.c (diskfs_truncate): Likewise. (block_extended): Likewise. (diskfs_grow): Likewise. * pager.c (diskfs_get_filemap): Accept additional parameter.
1999-09-041999-09-04 Thomas Bushnell, BSG <tb@mit.edu>Thomas Bushnell
* pager.c (find_address): If !ISREAD, then don't return errors for access past NP->allocsize, and clear *ADDR and *DISKSIZE. These can happen through harmless races against truncate. (pager_write_page): Don't print annoying messages for writes to unallocated disk. These can happen through harmless races against truncate, and so we should not pester the console with them.
1999-07-111999-07-09 Thomas Bushnell, BSG <tb@mit.edu>Thomas Bushnell
* dir.c (diskfs_get_directs): Use mmap instead of vm_allocate. * hyper.c (get_hypermetadata): Likewise. * pager.c (pager_read_page): Likewise.

* dir.c (diskfs_lookup_hard): Cope with error return from diskfs_get_filemap. * sizes.c (diskfs_grow): Likewise. * dir.c (diskfs_dirempty): Cope (poorly) with error return from diskfs_get_filemap. * sizes.c (diskfs_truncate): Likewise. (block_extended): Likewise. * pager.c (diskfs_get_filemap): If pager_create fails, return error to caller.
