Cover letter [Qemu-devel] [PATCHv6 0/6] introduce max_transfer_length
This series adds the basics for introducing a maximum transfer length to the block layer. Its main purpose is currently avoiding that a multiwrite_merge exceeds the max_xfer_len of an attached iSCSI LUN. This is a required bug fix.
Splitting up requests according to the max_transfer_length will follow in a later series.
v5->v6: - fix parentheses in Patch 1 [Max]
- rename helper function in Patch 3 [Max]
- cap the limits to highest power of 2 fitting in INT_MAX [Max]
- removed full stops in error messages in Patch 6 [Max]
v4->v5: - Added check for (a != 0 instead of !!a) [Max] and some comments [Eric]
- Correctly limited max_transfer_length to INT_MAX in Patch 3 [Max]
- Added Patch 5 and Patch 6.
v3->v4: introduce MIN_NON_ZERO to correctly calculate minimum of 2 limits. v2->v3: remove Patch 2 completely [Paolo]v1->v2: do not throw errors but generate trace events in Patch 2 [Paolo]
