      mutex: speed up generic mutex implementations · a8ddac7e
      Nick Piggin authored
      - atomic operations which both modify the variable and return something imply
        full smp memory barriers before and after the memory operations involved
        (failing atomic_cmpxchg, atomic_add_unless, etc don't imply a barrier because
        they don't modify the target). See Documentation/atomic_ops.txt.
        So remove extra barriers and branches.
      
      - All architectures support atomic_cmpxchg. This has no relation to
        __HAVE_ARCH_CMPXCHG. We can just take the atomic_cmpxchg path unconditionally
      
      This reduces a simple single threaded fastpath lock+unlock test from 590 cycles

      memcg: fix page_cgroup allocation · 94b6da5a
      KAMEZAWA Hiroyuki authored
      page_cgroup_init() is called from mem_cgroup_init(). But at this
      point, we cannot call alloc_bootmem().
      (and this caused panic at boot.)
      
      This patch moves page_cgroup_init() to init/main.c.
      
      Time table is following:
      ==
        parse_args(). # we can trust mem_cgroup_subsys.disabled bit after this.
        ....
        cgroup_init_early()  # "early" init of cgroup.
        ....
        setup_arch()         # memmap is allocated.
        ...
        page_cgroup_init();
        mem_init();   # we cannot call alloc_bootmem after this.
        ....
        cgroup_init() # mem_cgroup is initialized.
      ==
      
      Before page_cgroup_init(), mem_map must be initialized. So,
      I added page_cgroup_init() to init/main.c directly.
      
      (*) maybe this is not very clean but
          - cgroup_init_early() is too early
          - in cgroup_init(), we have to use vmalloc instead of alloc_bootmem().
          use of vmalloc area in x86-32 is important and we should avoid very large
          vmalloc() in x86-32. So, we want to use alloc_bootmem() and added page_cgroup_init()
          directly to init/main.c

      jbd: abort instead of waiting for nonexistent transactions · be07c4ed
      Duane Griffin authored
      The __log_wait_for_space function sits in a loop checkpointing
      transactions until there is sufficient space free in the journal.
      However, if there are no transactions to be processed (e.g.  because the
      free space calculation is wrong due to a corrupted filesystem) it will
      never progress.
      
      Check for space being required when no transactions are outstanding and
      abort the journal instead of endlessly looping.

      jbd: test BH_Write_EIO to detect errors on metadata buffers · 9f818b4a
      Hidehiro Kawai authored
      __try_to_free_cp_buf(), __process_buffer(), and __wait_cp_io() test
      BH_Uptodate flag to detect write I/O errors on metadata buffers.  But by
      commit 95450f5a "ext3: don't read inode
      block if the buffer has a write error"(*), BH_Uptodate flag can be set to
      inode buffers with BH_Write_EIO in order to avoid reading old inode data.
      So now, we have to test BH_Write_EIO flag of checkpointing inode buffers
      instead of BH_Uptodate.  This patch does it.

      ext3: add checks for errors from jbd · 2d7c820e
      Hidehiro Kawai authored
      If the journal has aborted due to a checkpointing failure, we have to
      keep the contents of the journal space.  Otherwise, the filesystem will
      lose uncheckpointed metadata completely and become inconsistent.  To
      avoid this, we need to keep needs_recovery flag if checkpoint has
      failed.
      
      With this patch, ext3_put_super() detects a checkpointing failure from
      the return value of journal_destroy(), then it invokes ext3_abort() to
      make the filesystem read only and keep needs_recovery flag.  Errors
      from journal_flush() are also handled by this patch in some places.

      jbd: fix error handling for checkpoint io · 4afe9785
      Hidehiro Kawai authored
      When a checkpointing IO fails, current JBD code doesn't check the error
      and continue journaling.  This means latest metadata can be lost from both
      the journal and filesystem.
      
      This patch leaves the failed metadata blocks in the journal space and
      aborts journaling in the case of log_do_checkpoint().  To achieve this, we
      need to do:
      
      1. don't remove the failed buffer from the checkpoint list where in
         the case of __try_to_free_cp_buf() because it may be released or
         overwritten by a later transaction
      2. log_do_checkpoint() is the last chance, remove the failed buffer
         from the checkpoint list and abort the journal
      3. when checkpointing fails, don't update the journal super block to
         prevent the journaled contents from being cleaned.  For safety,
         don't update j_tail and j_tail_sequence either
      4. when checkpointing fails, notify this error to the ext3 layer so
         that ext3 don't clear the needs_recovery flag, otherwise the
         journaled contents are ignored and cleaned in the recovery phase
      5. if the recovery fails, keep the needs_recovery flag
      6. prevent cleanup_journal_tail() from being called between
         __journal_drop_transaction() and journal_abort() (a race issue
         between journal_flush() and __log_wait_for_space()
