Subject: [PATCH 4/4] xfs: add the ability to reap entire inode forks
Date: Tue, 26 Mar 2024 18:57:47 -0700 [thread overview]
Message-ID: <171150381321.3217090.4300050106978699575.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171150381244.3217090.9947909454314511808.stgit@frogsfrogsfrogs>
From: Darrick J. Wong <djwong@kernel.org>
In preparation for supporting repair of indexed file-based metadata
(such as realtime bitmaps, directories, and extended attribute data),
add a function to reap the old blocks after a metadata repair finishes.
IOWs, this is an elaborate bunmapi call that deals with crosslinked
blocks by unmapping them without freeing them, and also scans for incore
buffers to invalidate.
