[PATCH] ext4: fix __ext4_xattr_set_credits()

From: Tahsin Erdogan
Date: Wed Jun 28 2017 - 17:48:03 EST


__ext4_xattr_set_credits() calculates journal credits needed for a
set xattr operation. Currently, credits needed for quota updates are
added only if ea_inode feature is enabled which is wrong. Fix this by
moving quota related additions to above ea_inode feature check.

Fixes: 74c5bfa651af ("ext4: xattr inode deduplication")
