Subject: [PATCH 11/21] xfs: refactor special inode roll out of xfs_dir_ialloc
Date: Tue, 31 Dec 2019 17:13:44 -0800 [thread overview]
Message-ID: <157784122440.1365473.15001800973344418611.stgit@magnolia> (raw)
In-Reply-To: <157784115560.1365473.15056496428451670757.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
In xfs_dir_ialloc, we roll the transaction if we had to allocate a new
inode chunk and before we actually initialize the inode. In the kernel
this requires us to detach the transaction's quota charge information
from the ichunk allocation transaction and to attach it the ialloc
transaction because we don't charge quota for inode chunks. This
doesn't exist in the userspace side of things, so pop it out into a
separately called function.
