[$] Removing GFP_NOFS

Date:
Wed, 05 Jun 2024 15:48:08 +0000

Description:
The GFP_NOFS flag is meant for kernel memory allocations that
should not cause a call into the filesystems to reclaim memory because there 
are
already locks held that can potentially cause a deadlock.  The "scoped
allocation" API is a better choice for filesystems to indicate that they
are holding a lock, so GFP_NOFS has long been on the chopping block , though
progress has been slow.  In a filesystem-track session at
the 2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit , Matthew Wilcox wanted to
discuss how to move kernel filesystems away from the flag with the eventual
goal of removing it completely.
