[PATCH 0/2] smb/client: fix emulated insert range handling

From: Huiwen He <[email protected]>

This series fixes two issues in the SMB3 FALLOC_FL_INSERT_RANGE
emulation.

Patch 1 fixes missing new EOF validation, which allowed RLIMIT_FSIZE to
be bypassed.

Patch 2 preserves hole semantics for inserted ranges, fixing xfstests
generic/064 against Samba and ksmbd.

In my Windows Server testing, aligned 64 KiB and 128 KiB insert ranges
were reported as holes, but generic/064 still fails because it uses
4 KiB inserts. Azure Files may not pass the test because it does not
support sparse files.

Thanks,
Huiwen
