riastradh | tmpfs: Nix trailing whitespace. No functional change intended.
|
| 1.13 |
| 11-Jun-2020 |
ad | uvm_availmem(): give it a boolean argument to specify whether a recent
cached value will do, or if the very latest total must be fetched. It can
be called thousands of times a second and fetching the totals impacts not
only the calling LWP but other CPUs doing unrelated activity in the VM
system.

ad | Rename uvm_free() -> uvm_availmem().

ad | uvmexp.free -> uvm_free()
|

maxv | Remove the roundups, they are incorrect and cause memcmp to wrongfully fail
because of uninitialized bytes at the end of the buffers.

Two fixes from rmind
- tmpfs_node_get: restore (decrement) the node count on the error path.
- tmpfs_bytes_max: save the value of uvmexp.freetarg (since it is
unlocked/racy).

martin | Make sure to expand "freepages" to 64bit before shifting to byte values -
on rump we may have all our virtual address space "free".

martin | Remove the hardcoded 4 MB free kernel memory limit and replace it
by uvmexp.freetarg, as discussed on tech-kern.
Main purpose is to make tmpfs usable (as far as possible) on small memory
machines.
This is a bit experimental, but we need to give it some real world exposure
to see how well it works.

christos | handle MNT_UPDATE
|
| 1.4 |
| 24-May-2011 |
rmind | branches: 1.4.4; 1.4.14; 1.4.18; 1.4.28;
- tmpfs_alloc_node/tmpfs_free_node: move inode limiting into tmpfs_node_get()
and tmpfs_node_put(), update outdated/wrong comments and move/add asserts.
- tmpfs_mount: check for the version of arguments a bit earlier.
|
| 1.3 |
| 19-May-2011 |
rmind | - tmpfs: do not create dirent/node pools per-mount, there is no need to.
- tmpfs_mount: fix a leak of mount structures in error path.
|
| 1.2 |
| 28-Jun-2010 |
rmind | branches: 1.2.2; 1.2.4; 1.2.6; 1.2.8;
tmpfs_bytes_max: use MIN() rather than min(), which returns int.
Spotted by Wolfgang Solfrank.

| 1.1 |
| 22-Jun-2010 |
rmind | Replace tmpfs_pool custom allocator code with a simpler layer for memory
accounting. Use wired memory (which can be limited) for meta-data, and
kmem(9) for string allocations.
Close PR/31944. Fix PR/38361 while here. OK ad@.
