* When pulling and unmounting an umass USB stick, the file systembluhm2016-03-271-4/+4
| | | | | | | | | | | | could end up in an inconsistent state. The fstype dependent mp->mnt_data was NULL, but the general mp was still listed as a valid mount point. Next access to the file system would crash with a NULL pointer dereference. If closing the device fails, the mount point must go away anyway. There is nothing we can do about it. Remove the workaround for the EIO error in the general unmount code, but do not generate any error in the file system specific unmount functions. OK natano@ beck@

* Implement VFS read clustering for MSDOSFS.mpi2016-01-132-51/+71
| | | | | | | | | | | | | | | | | | | | | The logic used in msdosfs_bmap() to loop calling pcbmap() comes from FreeBSD and is not really efficient but it is good enough since it is only called when generating I/O. With this diff I get a 100% improvement when reading big files from a crappy USB stick. With this and bread_cluster(9) modified to not re-fetch B_CACHED buffers, reading large contiguous files with chunk sizes of MAXPHYS is almost as fast as physio(9) on the same device. For a 'real world' example, when copying music files from a USB stick I see a speed jump from 15MB/s on -current to 24Mb/s with this diff. While here rename some 'lbn' variables into 'cn' to better reflect what we're dealing with. Tested by Mathieu, with support from deraadt@

| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

This may be the same as the special that was actually used for the mount (e.g. in the case of a device node) or it may be different (e.g. in the case of a DUID).

| | | | | | | | | | | _PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're fs-independent for us. Since we don't support latter three on any fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO symbols in <unistd.h> (via sys/unistd.h) with value -1.

* Cleanup VFS mount string handling:jsing2012-09-101-13/+10
| | | | | | | | | | | - Avoid using copyinstr() without checking the return value. - sys_mount() has already copied the path in, so pass this to the filesystem mount code so that it does not have to copy it in again. - Avoid copyinstr()/bzero() dance when we can simply bzero() and strlcpy(). ok krw@
