Subject: [PATCH 0/13] fs: Various I_DIRTY_* state handling fixes
Date: Fri, 13 Nov 2026 09:47:00 +0100 [thread overview]
Message-ID: <20261113083336.15152-1-jack@suse.cz> (raw)
Hello,
this series is a result of my audit of I_DIRTY_* state handling fixes. Over the
years some pointless code or code with smaller or larger bugs has accumulated
in filesystems around handling of inode dirty state. In particular testing
for I_DIRTY_PAGES is very subtle (and racy without holding i_lock), some places
forget that I_DIRTY_TIME also means inode has dirty metadata etc. So this
patch set removes direct checks of dirtiness state from filesystems and either
change them to directly testing PAGECACHE_TAG_DIRTY or to a helper function
which performs appropriate dirtiness check reliably.
