| |
I found several modifiable points while reading the code. Please review.
v3: v2 patches remain unchanged, and v3 adds 3 additional patches. <mm/memfd_luo: fix physical address conversion in put_folios cleanup> <mm/memfd_luo: remove folio from page cache when accounting fails> <mm/memfd_luo: fix integer overflow in memfd_luo_preserve_folios>
These three patches address issues identified by the AI review, with the review link as follows: https://sashiko.dev/#/patchset/20260323110747.193569-1-duanchenghao@kylinos.cn
v2: https://lore.kernel.org/all/20260323140938.ba8943a5247c14b17bc70142@linux-foundation.org/
As suggested by Pratyush Yadav, add patch <mm/memfd: use folio_nr_pages() for shmem inode accounting>. https://lore.kernel.org/all/2vxzqzpebzi2.fsf@kernel.org/
<mm/memfd_luo: optimize shmem_recalc_inode calls in retrieve path> Same as V1, no logic changes; depends on patch #1 for modifications.
<mm/memfd_luo: remove unnecessary memset in zero-size memfd path> No modifications have been made.
<mm/memfd_luo: use i_size_write() to set inode size during retrieve> Add consistency-related descriptions to the commit log.
v1: https://lore.kernel.org/all/20260319012845.29570-1-duanchenghao@kylinos.cn/
