f2fs: Use mapping->gfp_mask to get file cache for writing
On 32-bit architectures, when GFP_NOFS is used, the file cache for write operations cannot be allocated from the highmem and CMA. Since mapping->gfp_mask is set to GFP_HIGHUSER_MOVABLE during inode allocation, using mapping_gfp_mask(mapping) as the GFP flag of getting file cache for writing is more efficient for 32-bit architectures. Additionally, use FGP_NOFS to avoid potential deadlock issues caused by GFP_FS in GFP_HIGHUSER_MOVABLE Signed-off-by: Jiucheng Xu <jiucheng.xu@amlogic.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
