    [PATCH] hpfs: deadlock fixes · d9013aae
    Alexander Viro authored
    We used to have GFP_KERNEL kmalloc() done by the code that held hpfs
    lock on directory.  That could trigger a call of hpfs_write_inode() and
    deadlock; fixed by switch to GFP_NOFS.  Same for hpfs inodes themselves
    - hpfs_write_inode() calls iget() and that could trigger both the
    deadlocks (avoidable with very baroque locking scheme) and stack
    overflows (unavoidable unless we kill potential recursion here).
