disable loading f2fs module on PAGE_SIZE > 4KB
The following patch disables loading of f2fs module on architectures which have PAGE_SIZE > 4096 , since it is impossible to mount f2fs on such architectures , log messages are: mount: /mnt: wrong fs type, bad option, bad superblock on /dev/vdiskb1, missing codepage or helper program, or other error. /dev/vdiskb1: F2FS filesystem, UUID=1d8b9ca4-2389-4910-af3b-10998969f09c, volume name "" May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Invalid page_cache_size (8192), supports only 4KB May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Can't find valid F2FS filesystem in 1th superblock May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Invalid page_cache_size (8192), supports only 4KB May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Can't find valid F2FS filesystem in 2th superblock May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Invalid page_cache_size (8192), supports only 4KB which was introduced by git commit 5c9b469295fb6b10d98923eab5e79c4edb80ed20 tested on git kernel 4.17.0-rc6-00309-gec30dcf7f425 with patch applied: modprobe: ERROR: could not insert 'f2fs': Invalid argument May 28 01:40:28 v215 kernel: F2FS not supported on PAGE_SIZE(8192) != 4096 Signed-off-by: Anatoly Pugachev <matorola@gmail.com> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
