      f2fs: should use a temp extent_info for lookup · 22a341b4
      Jaegeuk Kim authored
      Otherwise, __lookup_extent_tree() will override the given extent_info which will
      be used by caller.

      f2fs: fix to avoid NULL pointer dereference in f2fs_issue_flush() · b3d83066
      Chao Yu authored
      With below two cases, it will cause NULL pointer dereference when
      accessing SM_I(sbi)->fcc_info in f2fs_issue_flush().
      
      a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
      release SM_I(sbi)->fcc_info,
      
      - mount -o noflush_merge /dev/vda /mnt/f2fs
      - mount -o remount,flush_merge /dev/vda /mnt/f2fs  -- kthread_run() fails
      - dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
      
      b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below
      testcase,
      
      - mount -o ro /dev/vda /mnt/f2fs
      - mount -o rw,remount /dev/vda /mnt/f2fs
      - dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
      
      In order to fix this issue, let change as below:
      - fix error path handling in f2fs_create_flush_cmd_control().
      - allocate SM_I(sbi)->fcc_info even if readonly is on.
