 Modified Files:
 	src/sys/ufs/lfs: lfs_accessors.h lfs_segment.c lfs_subr.c lfs_vfsops.c
 
 Log Message:
 Handle two causes of the panic "lfs_ifile: looping".  Repurpose the lfs_iflock
 to be locked with RW_WRITER while the segment lock is held, preventing
 updates to the Ifile while its blocks are being gathered; and allow more
 iterations than 10 before panicking, since we might need to rewrite the
 entire segment table one block per iteration.  Issue uncovered in the course
 of PR kern/60746.
