[PATCH 0/2] xfs: one extent per EFI

[Wengang Wang <wen.gang.wang@oracle.com>]

We are hitting the deadlock described in patch 1.
This patchset doesn't want to disturb the existing block allocation
routine, that would make the allocation routime even complex. Instead,
this patch avoids doing AGFL block allocation holding busy extents in current
memory transaction.

Patch 1 fixes the IO path and Patch 2 takes care of log recovery.

Wengang Wang (2):
  xfs: IO time one extent per EFI
  xfs: log recovery stage split EFIs with multiple extents
