    "I recently took maintainership of the befs file system [0]. This is
    the first time I send you a git pull request, so please let me know if
    all the below is OK.

    Salah Triki and myself have been cleaning the code and fixing a few
    small bugs.

    Sorry I couldn't send this sooner in the merge window, I was waiting
    to have my GPG key signed by kernel members at ELCE in Berlin a few
    days ago."

  • a441b0d09   block: remove remnant refs to hardsect ... Browse Code »

    commit e1defc4ff0cf57aca6c5e3ff99fa503f5943c1f1
    "block: Do away with the notion of hardsect_size"
    removed the notion of "hardware sector size" from
    the kernel in favor of logical block size, but
    references remain in comments and documentation.

    Update the remaining sites mentioning hardsect.

  • 5d097056c   kmemcg: account certain kmem allocations to memcg ... Browse Code »

    Mark those kmem allocations that are known to be easily triggered from
    userspace as __GFP_ACCOUNT/SLAB_ACCOUNT, which makes them accounted to
    memcg. For the list, see below:

    - threadinfo
    - task_struct
    - task_delay_info
    - pid
    - cred
    - mm_struct
    - vm_area_struct and vm_region (nommu)
    - anon_vma and anon_vma_chain
    - signal_struct
    - sighand_struct
    - fs_struct
    - files_struct
    - fdtable and fdtable->full_fds_bits
    - dentry and external_name
    - inode for all filesystems. This is the most tedious part, because
    most filesystems overwrite the alloc_inode method.

    The list is far from complete, so feel free to add more objects.
    Nevertheless, it should be close to "account everything" approach and
    keep most workloads within bounds. Malevolent users will be able to
    breach the limit, but this was possible even with the former "account
    everything" approach (simply because it did not account everything in
    fact).

  • 21fc61c73   don't put symlink bodies in pagecache into highmem ... Browse Code »

    kmap() in page_follow_link_light() needed to go - allowing to hold
    an arbitrary number of kmaps for long is a great way to deadlocking
    the system.

    new helper (inode_nohighmem(inode)) needs to be used for pagecache
    symlinks inodes; done for all in-tree cases. page_follow_link_light()
    instrumented to yell about anything missed.

  • 6e77137b3   don't pass nameidata to ->follow_link() ... Browse Code »

  • 680baacbc   new ->follow_link() and ->put_link() calling conventions ... Browse Code »

    a) instead of storing the symlink body (via nd_set_link()) and returning
    an opaque pointer later passed to ->put_link(), ->follow_link() _stores_
    that opaque pointer (into void * passed by address by caller) and returns
    the symlink body. Returning ERR_PTR() on error, NULL on jump (procfs magic
    symlinks) and pointer to symlink body for normal symlinks. Stored pointer
    is ignored in all cases except the last one.

    Storing NULL for opaque pointer (or not storing it at all) means no call
    of ->put_link().

    b) the body used to be passed to ->put_link() implicitly (via nameidata).
    Now only the opaque pointer is. In the cases when we used the symlink body
    to free stuff, ->follow_link() now should store it as opaque pointer in addition
    to returning it.

  • 8e19189ef   fs/befs/linuxvfs.c: check superblock before dump operation ... Browse Code »

    befs_dump_super_block was called between befs_load_sb and befs_check_sb.
    It has been reported to crash (5/900) with null block testing.

    This patch loads, checks and only dump superblock if it's a valid one
    then brelse bh.

    (befs_dump_super_block uses disk_sb (bh->b_data) so it seems we need to
    call it before brelse(bh) but I don't know why befs_check_sb was called
    after brelse. Another thing I don't understand is why this problem
    appears now).
