UML: fix hostfs build

2008-02-09T19:08:33+00:00

/home/bunk/linux/kernel-2.6/git/linux-2.6/fs/hostfs/hostfs_kern.c: In function 'hostfs_show_options':
/home/bunk/linux/kernel-2.6/git/linux-2.6/fs/hostfs/hostfs_kern.c:328: error: dereferencing pointer to incomplete type

We need to include mount.h to get vfsmount.

mount options: fix hostfs

2008-02-08T17:22:40+00:00

Add the "host path" option to /proc/mounts for UML hostfs filesystems.

The mount source (mnt_devname) should really be used for this, but not
easy to change now in a backward compatible way.

iget: stop HOSTFS from using iget() and read_inode()

2008-02-07T16:42:29+00:00

Stop the HOSTFS filesystem from using iget() and read_inode().  Provide
hostfs_iget(), and call that instead of iget().  hostfs_iget() then uses
iget_locked() directly and returns a proper error code instead of an inode in
the event of an error.

hostfs_fill_sb_common() returns any error incurred when getting the root inode
instead of EINVAL.

Note that the contents of hostfs_kern.c need to be examined:

 (*) hostfs_iget() should perhaps subsume init_inode() and hostfs_read_inode().

 (*) It would appear that all hostfs inodes are the same inode because iget()
     was being called with inode number 0 - which forms the lookup key.

uml: fix hostfs tv_usec calculations

2008-02-05T17:44:30+00:00

To convert from tv_nsec to tv_usec, one needs to divide by 1000, not multiply.

Get rid of an empty if statement which might look like a bug to a
casual reader.

UML: remove unnecessary hostfs_getattr()

2007-10-16T16:43:05+00:00

Currently hostfs_getattr() just defines the default behavior.

hostfs: convert to new aops

2007-10-16T16:42:57+00:00

This also gets rid of a lot of useless read_file stuff. And also
optimises the full page write case by marking a !uptodate page uptodate.

sendfile: remove .sendfile from filesystems that use generic_file_sendfile()

2007-07-10T06:04:13+00:00

They can use generic_file_splice_read() instead. Since sys_sendfile() now
prefers that, there should be no change in behaviour.
