hostfs: support rename flags

2014-08-07T18:40:09+00:00

Support RENAME_NOREPLACE and RENAME_EXCHANGE flags on hostfs if the
underlying filesystem supports it.

Since renameat2(2) is not yet in any libc, use syscall(2) to invoke the
renameat2 syscall.

mm + fs: store shadow entries in page cache

2014-04-03T23:21:01+00:00

Reclaim will be leaving shadow entries in the page cache radix tree upon
evicting the real page.  As those pages are found from the LRU, an
iput() can lead to the inode being freed concurrently.  At this point,
reclaim must no longer install shadow pages because the inode freeing
code needs to ensure the page tree is really empty.

Add an address_space flag, AS_EXITING, that the inode freeing code sets
under the tree lock before doing the final truncate.  Reclaim will check
for this flag before installing shadow pages.

um: hostfs: make functions static

2014-01-26T10:51:09+00:00

The hostfs_*() callback functions are all only used within
hostfs_kern.c, so make them static.

Rename simple_delete_dentry() to always_delete_dentry() and export it.
Export simple_dentry_operations, while we are at it, and get rid of
their duplicates

um: hostfs: Fix writeback

2013-09-07T08:38:29+00:00

We have to implement ->release() and trigger writeback from it.
Otherwise we might lose dirty pages at munmap().

hostfs: use kmalloc instead of kzalloc

2013-05-04T19:48:45+00:00

The inode info structure is zeroed at allocation with kzalloc, and then
all but one of the fields (including the largest, vfs_inode) are
initialised explicitly. Switch to using kmalloc and initialise the
remaining field too.
