Subject: mm: swap.h: Remove deleted field from comments
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d49ff1738026421c3129431ffc26d5c102180c54;p=users%2Fjedix%2Flinux-maple.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.
