kleink c1779f82c3 added advisory record locking support 1997-04-02 17:09:47 +00:00

mikel be4f5a32c1 use the proper entry count; from Yasufumi Itoh in PR kern/3175. 1997-02-20 05:04:05 +00:00
cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

cgd b02974b037 Jay Fenlason <hack@datacube.com>:
1: the fi_readers and fi_writers fields of the fifoinfo structure were not
being initialized to 0.  This caused the driver to not sleep the first
process to open the fifo--it thought there was already another process to
talk to (most of the time.)

2: fifo_open() was calling tsleep() without unlocking the inode of the fifo
file.  This caused *any* subsequent access to the file (even an ls (!)) to
hang forever.  Note that this bug was usually masked by bug #1 above.
