Instead of invalidating negative dentries during case-insensitive
lookups, mark them as such and let them be added to the dcache.
d_ci_revalidate is able to properly filter them out if necessary based
on the dentry casefold flag.

This patchset enables negative dentries for case-insensitive directories
in ext4/f2fs. It solves the corner cases for this feature, including
those already tested by fstests (generic/556). It also solves an
existing bug with the existing implementation where old ne

Introduce a dentry revalidation helper to be used by case-insensitive
filesystems to check if it is safe to reuse a negative dentry.
A negative dentry is safe to be reused on a case-insensitive lookup if
it was created during a case-insensitive lookup and this is no

Preserve the existing behavior for encrypted directories, by rejecting
negative dentries of encrypted+casefolded directories. This allows
generic_ci_d_revalidate to be used by filesystems with both features
enabled, as long as the directory is either casefolded or e
From: Gabriel Krisman Bertazi
Now that casefold needs d_revalidate and calls fscrypt_d_revalidate
itself, generic_encrypt_ci_dentry_ops and generic_ci_dentry_ops are now
equivalent. Merge them together and simplify the setup code.

Negative dentries support on case-insensitive ext4/f2fs will require
access to the name under lookup to ensure it matches the dentry. This
adds an optional new flavor of cached dentry revalidation hook to expose
this extra parameter.
I'm fine with extending d_reval

This flag marks a negative or positive dentry as being created after a
case-insensitive lookup operation. It is useful to differentiate
dentries this way to detect whether the negative dentry can be trusted
during a case-insensitive lookup.

Good day, dear maintainers,
We found a bug using a modified kernel configuration file used by syzbot.
We enhanced the coverage of the configuration file using our tool, klocalizer.
