Subject: [PATCH 0/4] ubifs: Add overlayfs support
Date: Tue, 13 Sep 2016 16:18:54 +0200 [thread overview]
Message-ID: <1473776338-18816-1-git-send-email-richard@nod.at> (raw)
To support overlayfs in a proper way a filesystem has to offer support
for DT_CHR, RENAME_WHITEOUT and RENAME_EXCHANGE.
While UBIFS supports DT_CHR it lacks support for RENAME_WHITEOUT and
RENAME_EXCHANGE. This patch series implement the missing bits.
RENAME_WHITEOUT itself depends on O_TMPFILE, therefore O_TMPFILE is now
also supported.
Richard Weinberger (4):
ubifs: Implement O_TMPFILE
ubifs: Implement RENAME_WHITEOUT
ubifs: Implement RENAME_EXCHANGE
ubifs: Use move variable in ubifs_rename()
