From cf2cb7845d6e101cb17bd62f8aa08cd514fc8988 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 20 Jun 2017 14:36:19 -0700 Subject: [PATCH] xfs: free cowblocks and retry on buffered write ENOSPC XFS runs an eofblocks reclaim scan before returning an ENOSPC error to userspace for buffered writes. This facilitates aggressive speculative preallocation without causing user visible side effects such as premature ENOSPC. Run a cowblocks scan in the same situation to reclaim lingering COW fork preallocation throughout the filesystem. Signed-off-by: Brian Foster Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
