[PATCH] file: Zero support for block devices and NFS 4.2
If we may not trim, we tried ZERO_RANGE, but this is not well supported
yet, for example it is not available on NFS 4.2. ZERO_RANGE and
PUNCH_HOLE are supported now on block devices, but not on RHRL 7, so we
fallback to slow manual zeroing there.
Change the logic to support block devices on RHEL 7, and file systems
that do not support ZERO_RANGE.
The new logic:
- If we may trim, try PUNCH_HOLE
- If we can zero range, Try ZERO_RANGE
- If we can punch hole and fallocate, try fallocate(PUNCH_HO...

[PATCH 0/3] file: Zero for block devices and older file systems
This is the second version to support efficient zero for block devices
on older kernels (e.g. RHEL 7.5), and file systems that do not support
yet FALLOC_FS_ZERO_RANGE (e.g. NFS 4.2).
Changes since v1:
- Split to smaller patches
- Skip linux only includes on other systems
- Skip code using BLKZEROOUT if the macro is not defined
- Try BLKZEROOUT only if the offset and count are aligned to device
