Hi,
After: 5a2be1288b514 ("vfs: Convert squashfs to use the new mount API")
We see this; when mounting a squashfs from a ubiblockdev:
root@iwg26-v2:/data/root# mount /dev/ubiblock0_6 /mnt
[ 39.884295] /dev/ubiblock0_6: Can't open blockdev
But the filesystem is mounted anyway...
I have tried checking the returned error code get_tree_bdev() -> blkdev_get_by_path() returns -EROFS.
I have also tried to see what happens in squashfs_get_tree() it will be re-run with the ro option set.
Which explains why the filesystem ends up mouted.
[ 39.889461] ####Custom debug: squashfs_get_tree -30
[ 39.906309] ####Custom debug: squashfs_get_tree 0
Fair enough it's after all a squashfs :)
But could the error message be better? Or just filter out the print when getting a EROFS?
Br,
/Sean
