2016-01-09fs:affs:Replace time_t with time64_tDengChao3-8/+9
The affs code uses "time_t" and "get_seconds()". This will cause problems on 32-bit architectures in 2038 when time_t overflows. This patch replaces them with "time64_t" and "ktime_get_real_seconds()". This patch introduces expensive 64-bit divsion in "secs_to_datestamp()", considering this function is not called so often, the cost should be acceptable.

2015-12-08replace ->follow_link() with new method that could stay in RCU modeAl Viro1-2/+2
new method: ->get_link(); replacement of ->follow_link(). The differences are: * inode and dentry are passed separately * might be called both in RCU and non-RCU mode; the former is indicated by passing it a NULL dentry. * when called that way it isn't allowed to block and should return ERR_PTR(-ECHILD) if it needs to be called in non-RCU mode. It's a flagday change - the old method is gone, all in-tree instances converted. Conversion isn't hard; said that, so far very few instances do not immediately bail out when called in RCU mode. That'll change in the next commits. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2015-12-08don't put symlink bodies in pagecache into highmemAl Viro3-3/+3
kmap() in page_follow_link_light() needed to go - allowing to hold an arbitrary number of kmaps for long is a great way to deadlocking the system. new helper (inode_nohighmem(inode)) needs to be used for pagecache symlinks inodes; done for all in-tree cases. page_follow_link_light() instrumented to yell about anything missed.

2015-09-10fs/affs: make root lookup from blkdev logical sizePranay Kr. Srivastava1-3/+5
This patch resolves https://bugzilla.kernel.org/show_bug.cgi?id=16531. When logical blkdev size > 512 then sector numbers become larger than the device can support. Make affs start lookup based on the device's logical sector size instead of 512.
