Acilan yeni bencerede ilk satir PATCH Basligi olacak sekilde kisaca yazilir. Toolun kendisi [PATCH] seklinde basliga eklentilerini kendisi yapmaktadir. Sonra patch anlatan body kismi eklenir. signoff alaninin altta kalmasina ozen gosterilir.

git format-patch -1 HEAD komutuyla HEAD gosterdigi yerden 1 adet patch cikarilir.
According to the documentation link above, the -1 flag tells git how many commits should be included in the patch;
-<n>
Prepare patches from the topmost commits.

Subject: [PATCH] Scripts: Fix for Parsing DMAR Region under Reserved
Section While kernel command parameters are intel_iommu=on intremap=on at
some machines, cat /proc/iomem shows DMAR region under reserved section.
This patch must be done for config creation to complete because of
generating DMAR region not found error although it exist. If this patch is
not apply, below error is throw by "config create" command whether
intel_iommu On or Off because "reserved" regions are currently excluded from
the generated config although DMAR region exists. Thus, DMAR under reserved
section must be parsed by parser.
