Subject: mm: swap.h: Remove deleted field from comments
X-Git-Tag: v6.18-rc1~130^2~300
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=85b8cec15034e07500a6e5b8a5aea8185a3d775a;p=thirdparty%2Fkernel%2Fstable.git

mm: swap.h: Remove deleted field from comments

The comment for struct swap_info_struct.lock incorrectly mentions fields
that have already been deleted from the structure.

Update the comments to accurately reflect the current struct
swap_info_struct.

There is no functional change.
