[PATCH v6 0/5] smb: fix fallocate and allocation accounting

From: Huiwen He <[email protected]>

Changes in v6:

- Rework patch 4 to remove the client-side statfs ENOSPC precheck. The
  server should report ENOSPC from the real allocation attempt; this fixes
  the xfstests generic/103 regression and keeps the generic/213 ENOSPC
  failure exposed with Samba "strict allocate = no".

- Add patch 5 to fix generic/213 on ksmbd by mapping SET_INFO
  -ENOSPC/-EFBIG to STATUS_DISK_FULL.
