Standardize the journal mode of symlink external block, from the
essentially data=journal mode to 'standard mode' like other metadata
blocks. (e.g. directory blocks and directory blocks...)
Thanks,
Yi.
v4->v3:
- Add a query cache 'no-wait' mode of ext4_getblk() and
ext4_map_blocks() to fix potential sleep problem in RCU context.
v3->v2:
- Retry if it fail in close-to-ENOSPC conditions.
- Use ext4_add_nondir() to add dir entry for no-fast symlink.
- Fix RCU walking for symlinks.
- Ensure nul-terminate when in ext4_get_link().
v2->v1:
- Add comment to explain the credits of creating symlink.
