From Fox Chen: The Path lookup is a very complex subject in VFS. The path-lookup document provides a very detailed guidance to help people understand how path lookup works in the kernel. This document was originally written based on three lwn articles five years ago. As times goes by, some of the content is outdated. This patchset is intended to update the document to make it more relevant to current codebase.

instead of lookup_real()/vfs_create(), i_op->lookup() and i_op->create() will be called directly. update vfs_open() logic should_follow_link is merged into lookup_last() or open_last_lookup() which returns symlink name instead of an integer. Signed-off-by:

get_link() is merged into pick_link(). i_op->follow_link is replaced with i_op->get_link(). get_link() can return ERR_PTR(0) which equals NULL. Signed-off-by:

WALK_GET is changed to WALK_TRAILING with a different meaning. Here it should be WALK_NOFOLLOW. WALK_PUT dosn't exist, we have WALK_MORE. WALK_PUT == !WALK_MORE And there is not should_follow_link(). Related commits: commit 8c4efe22 ("namei: invert the meaning of WALK_FOLLOW") commit 1c4ff1a8 ("namei: invert WALK_PUT logics") Signed-off-by:

no get_link() anymore. we have step_into() and pick_link(). walk_component() will call step_into(), in turn call pick_link, and return symlink name. Signed-off-by:

No inode->put_link operation anymore. We use delayed_call to deal with link destruction. Cookie has been replaced with struct delayed_call. Related commit: commit fceef393 ("switch ->get_link() to delayed_call, kill ->put_link()") Signed-off-by:

follow_link has been replaced by get_link() which can be called in RCU mode. see commit: commit 6b255391 ("replace ->follow_link() with new method that could stay in RCU mode") Signed-off-by:

Add macro name MAXSYMLINKS to the symlink limit description, so that it is consistent with path name length description above. Signed-off-by:

No filename_mountpoint any more see commit: commit 161aff1d ("LOOKUP_MOUNTPOINT: fold path_mountpointat() into path_lookupat()") Without filename_mountpoint and path_mountpoint(), the numbers should be four & three: "These four correspond roughly to the three path_*() functions" Signed-off-by:

traling_symlink() was merged into lookup_last, do_last(). do_last() has later been split into open_last_lookups() and do_open(). see related commit: commit c5971b8c ("take post-lookup part of do_last() out of loop") Signed-off-by:

path_mountpoint() doesn't exist anymore. Have been folded into path_lookup_at when flag is set with LOOKUP_MOUNTPOINT. Check commit: commit 161aff1d ("LOOKUP_MOUNTPOINT: fold path_mountpointat() into path_lookupat()") Signed-off-by:

No follow_managed() anymore, handle_mounts(), traverse_mounts(), will do the job. see commit 9deed3eb ("new helper: traverse_mounts()") Signed-off-by:

Fix think-o about which variable to find the Kbuild-configured shell. This has accidentally worked due to most shells setting $SHELL by default. Fixes: 51e46c7a ("docs, parallelism: Rearrange how jobserver reservations are made") Cc: stable@vger.kernel.org Signed-off-by:

Sphinx 3.0 works at this point (albeit slowly) so stop scaring people with a loud warning. We also don't need to babble about CJK support in the LaTeX build. Signed-off-by: -

The :doc:`foo` tag is auto-generated via automarkup.py. So, use the filename at the sources, instead of :doc:`foo`. Acked-by:
