| |
Greetings!
verified that the patches apply on linux-2.6.0-test6 and work as expected ...
FYI, this patch (hopefully) allows RO --bind mounts to 'behave' like other ro mounted filesystems, and I hope that they will be included in the mainline in the near future ;)
AFAIK, it handles the following cases as expected:
- open (read/write/trunc), create - link, symlink, unlink - mknod (reg/block/char/fifo), mkfifo - mkdir, rmdir - (f)chown, (f)chmod, utimes - ioctl (gen/ext2/ext3/reiser) - access, truncate
it doesn't handle update_atime() yet (Al Viro is still busy ;) and it doesn't change current intermezzo code (but this would be easy to add, because it's almost the same as the vfs_*()s at least regarding ro --bind mounts)
you can get them at:
