I found that 2.5.1 is OK, but 2.6 is not.

I reverted this commit, and then epoll is OK now.

This patch ensures QEMU won't terminate while hotplugging a device if the
global property cannot be set and errp points to error_fatal or error_abort.
While here, it also fixes indentation of the typename argument.

Now that we can support boxed commands, use it to greatly reduce the
number of parameters (and likelihood of getting out of sync) when
adjusting blockdev-backup parameters.

This is a preparatory patch, which continues the general trend of the
transition to the byte-based interfaces. bdrv_check_request() and
blk_check_requestis no longer used, so we can remove.

There are no block drivers left that implement the old
.bdrv_write_compressed interface, so it can be removed. Also now we have
no need to use the bdrv_pwrite_compressed function and we can remove it
entirely.

Now that the function uses a vector instead of a buffer, there is no

For bdrv_pwrite_compressed() it looks like most of the code creating
coroutine is duplicated in bdrv_prwv_co(). So we can just add a flag
(BDRV_REQ_WRITE_COMPRESSED) and use bdrv_prwv_co() as a generic one.
In the end we get coroutine oriented function for write compressed by
Rather than asserting that nbdflags is within range, just give

This series extracts a couple of bug fixes that should be included
in 2.7, out of my earlier v5 NBD series [1] that was deemed too
large and too late. Then it tackles the promised regression fix
reported by Peter for Dell Equallogic iSCSI SANs with their unusual
non-power-of-2 unmap granularity.
Make it obvious which macros are safe in which situations.
Useful since QEMU_ALIGN_UP and ROUND_UP both purport to do
the same thing, but differ on whether the alignment must be
a power of 2.
