- This bit is not changed by vendor driver, and should be left alone.
- The documentation implies this a debug bit.
- 0 = WAKE# only asserted when VMAIN not available
- 1 = WAKE# is depend on wake events and independent of VMAIN.

-
-If the BMC gets reset, it will return 0x80 response errors. In this case,
-it is probably a good idea to restore the IPMI settings.

-xfs: force buffer writeback before blocking on the ilock in inode reclaim
-
-If we are doing synchronous inode reclaim we block the VM from making
-progress in memory reclaim. So if we encouter a flush locked inode
-promote it in the delwri list and wake up xfsbufd to write it out now.
-Without this we can get hangs of up to 30 seconds during workloads hitting
-synchronous inode reclaim.
-
-The scheme is copied from what we do for dquot reclaims.
