* [PATCH 15/17] kill the vfs_flags member in struct bhv_vfs

From: Christoph Hellwig @ 2007-08-23 19:40 UTC (permalink / raw)
To: xfs
All flags are added to xfs_mount's m_flag instead. Note that the 32bit
inode flag was duplicated in both of them, but only cleared in the
mount when it was not nessecary due to the filesystem beeing small enough.
Thus this patch introduces a slight behavior change in that the 32bit
inodes option is only present in the /proc/<pid>/mounts output if
actually nessecary but not if it was on the command line but isn't
actually in effect.

Hmmm - it looks like it actually prints inode64 in that case.

So if the XFS_MOUNT_32BITINODES is not set, we print "inode64" in
/proc/<pid>/mounts, and:

On mount, we enter here in with XFS_MOUNT_32BITINODES set unless
the inode64 mount option is set. Assuming 256 byte inodes we
end up with:
entry fs_size exit /proc/mounts
set <1TB clear ...,inode64,... wrong
set >1TB set nothing correct
clear any clear ...,inode64,... correct
And then we have the growfs case, which *always* sets the
XFS_MOUNT_32BITINODES flag before initialising thenew ags and
that means we see:
entry fs_size exit /proc/mounts
set <1TB clear ...,inode64,... wrong
set >1TB set nothing *possibly wrong*
The issue here is that if we supplied inode64 on the command line,
then grow the filesystem to something more than 1TB (even if it
started at more then 1TB) we turn on inode32 mode. That is
wrong. If growfs does not set the flag:
entry fs_size exit /proc/mounts
clear <1TB clear ...,inode64,... wrong
clear >1TB clear ...,inode64,... *possibly wrong*
We can be enabling inode64 on 32bit systems incorrectly.
So I think a second flag really is needed here to ensure
the correct mode is preserved for the grow case, and that
would ensure that we don't have a change in /proc/mounts
output, too.

"read-only fs"?
