My laptop has been behaving strangely with 4.2-rc2. Once I log in to my X session, I start getting all kinds of strange errors from applications and see this in my dmesg: VFS: file-max limit 8192 reached Could this be from CONFIG_DEFERRED_STRUCT_PAGE_INIT=y? files_init() seems top be sizing files_stat.max_files from memory sizes. vfs_caches_init() uses nr_free_pages() to figure out what the "current kernel size" is in early boot. *But* since we have not freed most of our memory, nr_free_pages() is low and makes us calculate the reserve as if the kernel we huge. Adding some printk's confirms this. Broken kernel: vfs_caches_init() mempages: 4026972 vfs_caches_init() reserve: 4021629 vfs_caches_init() mempages (after reserve minus): 5343 files_init() n: 2137 files_init() files_stat.max_files: 8192 Working kernel: vfs_caches_init() mempages: 4026972 vfs_caches_init() reserve: 375 vfs_caches_init() mempages2: 4026597 files_init() n: 1610638 files_init() files_stat.max_files: 1610638 Do we have an alternative to call instead of nr_free_pages() in vfs_caches_init()? I guess we could save off 'nr_initialized' in memmap_init_zone() and then use "nr_initialized - nr_free_pages()", but that seems a bit hackish. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
