Correct. Here's the series I'm talking about (sorry for not including a link in the original mail): https://lists.01.org/pipermail/linux-nvdimm/2015-December/003259.html The only patch that touches ext4 is patch 6/7, which is a 4 line change to hook into the ext4_dax_pfn_mkwrite() function and have it call dax_pfn_mkwrite(). Jan's series added ext4_dax_pfn_mkwrite(), which is my dependency. > > I'm just trying to figure out what I should use as a baseline for my changes > > since I need to build on Jan's patches but obviously don't want to include new > > ext4 code with my pull request (which I will send after you send yours). :) > > Please use the "master" branch from the ext4 tree as your baseline. > Normally dev is a rewinding branch, but for these sorts of situations > I'll guarantee that everything between origin..master will be stable, > while commits between master..dev may be rewound or dropped to fix > bugs/regressions: > > * dde86e3 - (HEAD -> guilt/origin, dev) ext4 crypto: add missing locking for keyring_key access (10 hours ago) > * 0969c39 - ext4 crypto: add ioctls to allow backup of encryption metadata (10 hours ago) > * 843848f - ext4 crypto: add ciphertext_access mount option (10 hours ago) > * ba5843f - (master) ext4: use pre-zeroed blocks for DAX page faults (3 days ago) > * c86d8db - ext4: implement allocation of pre-zeroed blocks (3 days ago) > * 53085fa - ext4: provide ext4_issue_zeroout() (3 days ago) > * 2dcba47 - ext4: get rid of EXT4_GET_BLOCKS_NO_LOCK flag (3 days ago) > * e74031f - ext4: document lock ordering (3 days ago) > * 0112784 - ext4: fix races of writeback with punch hole and zero range (3 days ago) > * 32ebffd - ext4: fix races between buffered IO and collapse / insert range (3 days ago) > * 17048e8 - ext4: move unlocked dio protection from ext4_alloc_file_blocks() (3 days ago) > * ea3d720 - ext4: fix races between page faults and hole punching (3 days ago) > > Jan's patches have gone through multiple rounds of testing and I'm > quite confident there are no bugs or regressions that can't be dealt > with using follow up patches.
