Cover letter [PATCH 0/2] xfs: handle mount failures more cleanly

Hi folks,

This is the XFS side of the "fs: don't scan the inode cache before SB_BORN is set" changes to handle mount failures more cleanly. This addresses teh use-after-free problems that can occur when xfs_fs_fill_super() fails, frees the xfs_mount structure but then leaves the VFS superblock pointing to it.

Th efirst patch is the mount delay sysfs option I've been using to test this. I'll post the fstest that uses it in a minute.

Cheers,

Dave.
