Subject: Bind Mount Extensions (RO --bind mounts)
Date: Tue, 23 Sep 2003 17:54:39 +0200 [thread overview]
Message-ID: <20030923155439.GA7470@DUK2.13thfloor.at> (raw)
Hi All!
just verified that the patches still apply on
linux-2.6.0-test5-bk9 and linux-2.4.23-pre5
without any issues ...
FYI, this patch (hopefully) allows RO --bind mounts
to 'behave' like other ro mounted filesystems ...
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:
