[PATCH v4 0/7] smb/client: fix fallocate and allocation accounting

[Huiwen He <huiwen.he@linux.dev>]

From: Huiwen He <hehuiwen@kylinos.cn>

Changes in v4:

- Add new patch 1 to refresh i_blocks after successful duplicate-extents.
  This fixes stale st_blocks after reflink and avoids the generic/370
  swapon hole-check regression.

The following patches from v2 have already been merged into cifs-2.6.git for-next:
  - smb/client: do not account EOF extension as allocation
  - smb/client: preserve errors from smb2_set_sparse()
  - smb/client: name the default fallocate mode

Thanks,
