      ext4: remove expensive flush on fast commit · e9f53353
      Daejun Park authored
      
      
      In the fast commit, it adds REQ_FUA and REQ_PREFLUSH on each fast
      commit block when barrier is enabled.  However, in recovery phase,
      ext4 compares CRC value in the tail.  So it is sufficient to add
      REQ_FUA and REQ_PREFLUSH on the block that has tail.

      ext4: fix bug for rename with RENAME_WHITEOUT · 6b4b8e6b
      yangerkun authored
      
      
      We got a "deleted inode referenced" warning cross our fsstress test. The
      bug can be reproduced easily with following steps:
      
        cd /dev/shm
        mkdir test/
        fallocate -l 128M img
        mkfs.ext4 -b 1024 img
        mount img test/
        dd if=/dev/zero of=test/foo bs=1M count=128
        mkdir test/dir/ && cd test/dir/
        for ((i=0;i<1000;i++)); do touch file$i; done # consume all block
        cd ~ && renameat2(AT_FDCWD, /dev/shm/test/dir/file1, AT_FDCWD,
          /dev/shm/test/dir/dst_file, RENAME_WHITEOUT) # ext4_add_entry in
          ext4_rename will return ENOSPC!!
        cd /dev/shm/ && umount test/ && mount img test/ && ls -li test/dir/file1
        We will get the output:
        "ls: cannot access 'test/dir/file1': Structure needs cleaning"
        and the dmesg show:
        "EXT4-fs error (device loop0): ext4_lookup:1626: inode #2049: comm ls:
        deleted inode referenced: 139"
      
      ext4_rename will create a special inode for whiteout and use this 'ino'
      to replace the source file's dir entry 'ino'. Once error happens
      latter(the error above was the ENOSPC return from ext4_add_entry in
      ext4_rename since all space has been consumed), the cleanup do drop the
      nlink for whiteout, but forget to restore 'ino' with source file. This
      will trigger the bug describle as above.
